The glow relay is situated above the alternator and starting motor on the 2012 Hyundai Sonata. Along with the other glow plugs, this is located on the left side. In actuality, it is located inside the main relay box. The timings, electrical current, and duration for which the glow plugs must be powered are determined by the glow plug relay. It carries out all of these tasks by receiving commands from the ECU, your vehicle’s engine control unit. Your car’s glow plug relay replacement could cost you anything from $75 to $150. A malfunctioning glow plug relay could make it difficult for you to start the car. Typically, this is true when it is cold outside.

2018 Sante Fe, throwing a p1326 Glow Relay Short Circuit
Mechanic’s Helper: Before I connect you, is there anything else the Hyundai mechanic needs to know? You can be confident that they will be able to assist you.
Hello there, I’ll be assisting you; I’m so sorry to hear about the problems with the Hyundai. My name is ***** *****. I am aware of how frustrating dealing with engine codes can be. Does the car still function as it should? Just the code is already set?
Yes, it functions properly. has not been knocking, and it has not experienced any difficulty with acceleration; it only recently began after my wife used a car wash.
Okay okay, so this won’t be a serious situation. But that code description is inaccurate. Since your vehicle is powered by gasoline, it lacks a glow relay. This code, which is unique to Hyundai, denotes a problem with the knock sensor circuit. Since it was usual for the wiring harness leading to the knock sensor to develop problems and set this code, Kia/Hyundai released a service bulletin and an extended warranty with this code. If you want to know if you are protected by this extended warranty, you need go to your nearby dealer. If not, anticipate to need to replace or repair the cabling leading to that knock sensor, and while you are having that done, I would suggest changing the sensor as well.
P1326 (Glow Relay Short Circuit) keeps appearing for me, and I also…
Mechanic’s Helper: The engine misfiring is indicated by such code. Before I connect you, is there anything else the Hyundai mechanic needs to know? You can be confident that they will be able to assist you.
Hello there, I’ll be assisting you; I’m so sorry to hear about the problems with the Hyundai. My name is ***** *****. I am aware of how frustrating it can be to deal with engine problems, particularly misfires. Whom am I now chatting with?
Okay, many thanks. I’m afraid this is likely engine mechanical damage. P1326 is a code unique to Hyundai and has to do with the knock sensor, not the glow plug. On this generation of Hyundai vehicles, the engine would frequently experience rod knock, which would cause misfires and set this code. In most cases, rebuilding or replacing the engine is required to resolve the problem. It’s worth getting in touch with the dealer to see if they will pay the engine replacement in this case because Hyundai did provide an extended warranty and recalled several of these engines.
The number 1 coil pack and all spark plugs have been replaced, however the message “Cylinder 1 Misfire” is still shown. Is the rod bearing to blame for that?
The new ignition parts likely fixed the spark blowing out problem as engine load increased, but they did not repair the engine damage.
Describe the glow relay.
A glow plug relay: what is it? The glow plug control device turns on and off the current for the glow plugs using a glow plug relay. The circuit will require more current the more glow plugs being watched by a control device.
Why do glow plug relays malfunction?
The glow plug relay is susceptible to natural wear and tear over time, like most other auto parts. Extreme heat exposure, varying electrical currents, and malfunctioning injectors can all contribute to speeding up the process.
Maintaining regular maintenance and getting your Mercedes serviced as soon as you detect any performance changes will help you get the most life out of it.
How can I tell whether my glow plug relay is operating properly?
- The glow plug’s power cable should be disconnected. If you don’t do this, you’ll measure all the glow plugs’ resistance at once rather than just the one you want to test.
- Switch to the “resistance” or “O” mode on the multimeter and turn it on.
- Connect one test lead from a multimeter to the engine’s ground (preferably near the glow plug).
- The (power supply) terminal on the top of the glow plug should receive the other lead.
- Look at the multimeter’s display to see the outcome. Keep in mind that a resistance of less than 6O often denotes a “excellent” glow plug.
- Disconnect the glow plugs.
- Remove the test lead from the glow plug power source.
- Reattach the power cord to the glow plug.
- For each glow plug on an engine, repeat steps 5–9 once more.
When the glow plug caution light is on, can I drive my car?
If you must continue driving when a glow plug light is flashing, drive slowly and try to limit your exposure to high speeds. An engine will frequently enter “safety mode,” and you may notice a decrease in performance.
Can glow plugs prevent a car from starting?
There are numerous signs of defective or failing diesel glow plugs. You should make an appointment with your automotive mechanic for service if your car exhibits any of these problems.
- One of the initial warning indications of glow plug issues is typically an engine that is misfiring. Glow plug issues prevent the engine from firing properly since they don’t produce the heat required for diesel combustion.
- A common sign is also the engine’s performance being compromised. The engine’s entire performance will be impacted if the gasoline and compressed air don’t ignite properly, leading to a misfire. Low acceleration when you press firmly on the gas pedal is a frequent issue. When you let off the gas pedal while driving a diesel vehicle, the engine won’t move forward.
- Misfires in the engine, which are both frequent indicators of worn-out or defective glow plugs, might result in a loss of power. Power loss may get so severe that the car won’t even start, leaving you stranded.
- A further typical symptom is difficult starting. Diesel engines rely on the cylinder pressures to ignite the diesel fuel combination, as opposed to gas engines, which require a spark to ignite the fuel mixture. If the glow plugs break, the engine must overcome the extra pressure to ignite the mixture. It frequently leads to difficult starting.
- Black smoke could be released from the exhaust. When glow plugs are defective, they may interfere with the delicate diesel combustion process, causing the engine to produce black smoke that is emitted from the tailpipe. Black smoke should be appropriately diagnosed because there are numerous different causes of it.
- Another typical indication is decreased fuel economy. The engine will have to work harder if its performance is compromised in order to try to keep up with the demands of the road. As a result, your car’s mileage will decline and its fuel economy will suffer. You will need to spend more money to keep your car on the road because your miles per gallon will be lower. You shouldn’t be surprised if your automobile starts to exhibit decreased fuel efficiency after exhibiting other symptoms, and you should take it to a reputable repair as soon as you can.
Glow plugs are a standard feature of diesel engines and are crucial to the engine’s operation and starting. You should get your car evaluated by a skilled automotive technician to identify the source of the issue and establish whether the glow plugs need to be changed if you see any of the aforementioned symptoms or if you suspect glow plug issues.
How many glow plugs are there in a car?
Diesel engines employ glow plugs as heating components to keep the engine warm during cold starts. When diesel engines are warm compared to when they are cold, they start significantly more quickly due to the fuel’s instantaneous ignition and lack of external flame (such as an electric spark). The engine will splutter and jerk at idle and emit black smoke if you don’t have glow plugs and let the engine run before driving.
Depending on the engine’s maker, different engines use different numbers of glow plugs. Six is most typical, with four used for starting and two for running. The time it takes for them to heat up varies depending on the manufacturer and might be anywhere between 3 and 30 minutes after electricity is connected. The engine’s starting time will decrease as the number of glow plugs increases.
Does a fuse exist for glow plugs?
The factory does not include a replaceable fuse for the high current side of the glow plug system. Fusible links are used in the stock system.
Verify whether there is electricity on the glow plug relay’s battery side. You have a blown fusible link if there is no power there. The wire itself incorporates the fusible link. They roughly like little black inline fuse holders. Gently pull on the wires where they enter the fusible link to examine them. If they do, the link has malfunctioned internally as a result of a short someplace, preventing it from doing its job and burning out and preventing the total destruction of your truck.
Never take the circuit’s fusible link out. To restore protection in that circuit if the link is blown, you must replace it with a new link of the appropriate size.
What governs a diesel engine’s glow plugs?
To regulate glow plug functioning and improve engine performance, the glow plug control unit decodes data from the engine control unit (ECU). It determines the amount of electrical current consumed and when glow plugs are used (which in turn determines the temperature)
What occurs if a glow plug malfunctions?
The engine won’t start unless the damaged glow plug is correctly replaced by removing the cylinder head. Doing so will disrupt the seal and cause the cylinder to lose compression.
Glow plug replacement is it simple?
When the engine is cold, glow plugs are employed in diesel engines to assist heat the fuel before it enters the combustion chamber. They are situated atop the cylinders and are powered by the battery’s full 12 volts. They are regularly used, and the amount of time they are utilized depends on the weather where you reside. Glow plug replacement is likely to be significantly more frequent for cars in colder climates, while glow plug lifespan in warmer climates can exceed 100,000 miles. Glow plugs are a difficult component to utilize because of constant use and large temperature variations. Basic indications of a failing glow plug are rough starts or misfires when beginning, smoking during starting, and difficulty starting in cold temperatures. With the appropriate tools, they are typically fairly inexpensive and simple to replace.
