2013 Express 2500.

Been having issues with an intermittent service tire pressure monitor system light with one particular sensor. Half the time the sensor shows up, half the time it does not.

I thought I replaced the defective sensor (GM 13598771), but it turns out they didn't reprogram the TPMS sensors during the last rotation, so I replaced the wrong wheel's sensor.

However, I cannot get the van to recognize the new sensor or any other sensor for that matter. The van simply never chirps or gives any indication it recognized the new sensor, even if I let air out of the tire with the new sensor or any of the old sensors.

I follow this procedure:
Set the parking brake.
Turn the ignition switch to RUN with the engine off.
Using the DIC, press the vehicle information button until the RELEARN TIRE POSITIONS message displays. If your vehicle does not have the DIC buttons, press the trip odometer reset stem located on the instrument panel cluster until the RELEARN TIRE POSITIONS message displays.
If your vehicle has the DIC buttons, press the set/reset button. The horn will sound twice to indicate the TPMS receiver is ready, and the TIRE LEARNING ACTIVE message will display. If your vehicle does not have the DIC buttons, press and hold the trip odometer reset stem until the horn chirps twice and the TIRE LEARNING ACTIVE message is displayed.
Start with the driver's side front tire.
Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for five seconds, or until a horn chirp sounds. The horn chirp, which make take up to 30 seconds to sound, confirms that the sensor identification code has been matched to this tire and wheel position. To decrease air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage, or a key.
Proceed to the passenger's side front tire, and repeat the procedure in Step 6.
Proceed to the passenger's side rear tire, and repeat the procedure in Step 6.
Proceed to the driver's side rear tire, and repeat the procedure in Step 6.
After hearing the confirming horn chirp for the driver's side rear tire, the horn chirp will sound two more times to signal the tire learning mode is no longer active. Turn the ignition switch to LOCK.
Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label.
Put the valve caps back on the valve stems

 

There's already a post covering this. Search my posts for TPMS

 

Right.

I guess I just need the relearn tool. Found a cheap one amazon that works. Weird that the instructions say letting air out/adding air is all you need.

 

One of the sensors on my Chevy Express van when out the other day (started reporting --). So I get a GM replacement (part no # 13598771) installed. The old one was from 2020, so I was surprised it already died.

Use the programming tool to program all 4 sensors, it's new sensor is reporting 0psi, all the other sensors are working properly. I ask the amazon seller for a replacement, he walked me through some troubleshooting steps first.

First procedure was called "faulting the system", which was:
* Put it in TPMS learn mode
* When horn honks shut off car
* Remove key
* Open door
* Close door
* Start, should see all --'s for all 4 sensors

That of course, didn't work, the new sensor started reporting -- instead of 0psi. The rest of the sensors were reporting the correct tire pressure.

He told me to google the "Soft reset" procedure and perform that, but I haven't been able to find it. He said for a 07-10 express, the procedure was:
* Disconnect battery
* Touch and hold the 2 battery terminals together for 90 seconds
* Reconnect battery
* Perform fault tpms system
* once you see all dashes it's good to to program

Anyone know what the proper procedure is for the 2013?

 

I've never heard of a soft reset

A service replacement tire pressure sensor is shipped in OFF mode. In this mode the sensor unique identification code cannot be learned into the remote control door lock receiver (RCDLR) memory. The sensor must be taken out of OFF mode by spinning the tire/wheel assembly above 32 km/h (20 mph) in order to close the sensors internal roll switch for at least 10 seconds.


In general, a wheel needs to be rolling to transmit pressure information.
If pressure information has been lost, or the DIC shows dashes, then driving the vehicle above 40 km/h (25 mph) for at least 2 minutes will reactivate the sensors.

Sounds defective.

 

Took it to tire shop for it's normal rotation the other day. Despite them trying to sell me on a $300+ TPMS job, the sensor magically started working.

But then after driving for 20-30 minutes, it went back to reading 0psi.

So I went to the guy on the corner, paid him $20 cash to change it out. And the new sensor reads the tire pressure PSI instantly AND knows what's wheel it is.. What's odd is it didn't need programing. Guess I'll find out soon enough if he actually changed it out, or left the old bad one in there.

 

Sensor worked for about 2 hours, then started reading --. Used the relearn tool to set all the pressure sensors and it seemed to work for several hours of operation after that. However, occasionally, it will rapidly switch between reporting 0psi then the actual tire pressure. But 95% of the time, sensor is working good.

I did get the sensor off Amazon, which seems to be considerably cheaper ($12) than most other sources ($40-50+). It did come in seemingly genuine GM packaging, etc.

Are these sensors known for being flaky or am I just unlucky?

 

I also have a 2013 model, and I'm still running on the factory sensors. Zero issues so far.

 

I have one sensor that went flaky last year. Bought an Amazon sensor "FindAuto"
It worked for a short time, then would not connect on the first trek of the morning, They sent me another. It did the same thing after a while. Just redid it again with a red one -Moresensor. SO far so good. The other 3 still no issue. Didn't use anything else to relearn it. Just the button on the dash.
