How many times have we had the tire light come on, whether due to rotating tires, changing wheels, etc? In the past, there was no way of resetting the light unless we brought it to the dealer, which would cost 50-150 bucks. I didnt want to pay for something that would've taken anyone 5 minutes to do. After doing a lot of research, I finally found a DIY method to reset it using only a paper clip.

Step 1: Set the tires to the following pressures, they have to be exact:

Tire position Tire pressure kPa (kg/cm2, psi)
Front LH 240 (2.4, 34)
Front RH 220 (2.2, 31)
Rear RH 200 (2.0, 29)
Rear LH 180 (1.8, 26)

Step 2: Locate the TPMS interface plug. This is a white female plug that is attached to the OBD II wire loom under the dash right about where your left knee would be when sitting in the driver's seat. You may have to cut the tape that is holding the TPMS interface plug to the OBD II wire loom.


Step 3: Attach a paper clip or wire into the interface plug.

Step 4: Put your key in the ignition and turn it to the last click before the engine starts. This is the KOEO position (Key On, Engine Off).

Step 5: Tap the end of the paper clip (the end NOT in the interface plug, duh!) on any exposed ground (metal) 6 times.

Step 6: If you completed step 5 then the TPMS warning light will start to slowly flash and you have activated the TPMS relearn process. If it flashes fast that's not right. If yours isn't flashing slowly then check your connections, turn the ignition off and start over at step 4.

Note: if you're having trouble getting it into the relearn mode, try grounding the connector, turn the car on, then turn the car off while still grounding it. Then repeat the above steps.

Step 7: Once you confirm the lights do not stop flashing, step on the clutch/brake and start the car. Do not turn the car to OFF position. Start driving >25mph until the light goes out. It could take as long as ten minutes.

Step 8: The light will quickly come back on due to the low tire pressures. Refill your tires to the correct pressure.

Step 9: Donate 30 bucks to me for saving you >$50 at the dealership for each reset.



If you are having problems with the above procedures:

If the instructions did not work for you, there might be a problem with one of your sensors. To find out, you need to enter the diagnostic mode.

To do that, first turn the car to the on position and ground terminal of the tire pressure warning check connector. The malfunction location is indicated by the low tire pressure warning lamp blinking.

Refer to the following chart to find out the problem:




After you are done reading the code, you can turn off the car while the connector is still grounded. This will clear the stored codes. Then repeat the steps in the top of the page.

I have a few questions since i need to do this.

1. Have you done this and confirmed it worked?
2. Is there only 1 pin hole to stick the clip into? I highly doubt it, so which pin do we put the clip into?
3. Since we dont have a key, for step 4 do we just put it to ON?


and Thanks!

1. Confirmed working by myself and wakeboardr116!

2. There is only 1 pin. It is explicitly stated in the factory service manual, that you ground this pin when you want to enter the TPMS diagnostic mode. However, they do not tell you that you can reprogram the sensors this way.

3. Yes, just put the car to on.

I will update this thread once i confirm it tonight!

Photos of the TPMS interface plug please.

If I can make this work, I WILL make a small donation. Seriously. PM me your Paypal.

I am about to throw 20s on my car.if you have figured out away around having to go to the dealer everytime you do a tire/wheel change.

if it does work,there are alot of people incluing myself that owe you some $$.

I found the plug. Mine is behind the hood release towards the firewall. I will try this in 20 minutes and let you know if it worked.

I got so excited at the idea I couldn't wait. I need to get one sensor installed and get them reset. I called the Local Nissan dealer nearby and he quoted me $94 for a reset only, not installing it. This will save me a bunch if I can DIY.

Anyway, here's a quick snap I took of a plug that may be it. It's impossible to tell from this photo, but asd yo9u can see it's directly above the OBD II port. It's on the left side, not the right in my 08 coupe, taped off to the OBD II harness about a couple of inches up. Do you think this is it?

My tpms light has been showing the malfunction light for a while. Is this the same thing as it needing to be reset? Everytime I turn the car on it blinks for 60 seconds then stays lit permenatly. Would this procedure reset it? I already took it to the dealer once and they replaced the sensors under warranty but it came back.

It could be. While setting up my car computer, I let the car idle for a long time. The TPMS light came on after a while. The pressure sensors do not send signal to the BCM when the tires do not spin. After not getting a signal for a long time, the BCM triggers the light, thinking the sensors are no longer present. Maybe this happened to you too?

In any case, try the reset procedure. If you just ground the TPMS pin, it will flash diagnostic codes. Depending on the number of flashes, it will report what malfunction is detected in the system.
