TPMS on a Vauxhall Astra GTC

Hometyre Milton Keynes attended to a customer's request for 2 new rear tyres to be fitted to a Vauxhall Astra GTC in Middleton Milton Keynes.

When I arrived the customer explained to me that he also had a problem with his tyre pressure monitor system (TPMS). The near side front tyre was not displaying any pressures. I got out my I Sensor TPMS reader to read the sensor. There was no problem picking up the sensor, but it was not displaying on the dashboard menu. I then tried to read the near side rear sensor and found that this sensor was not transmitting a signal. With this in mind I discovered out that someone had moved the front wheels to the back and not reprogrammed the sensors.

I removed the rear wheels and to replace the tyres. When I removed the near side rear tyre, I found that the sensor was damaged, problem solved!

I then slotted a new I Senor into my programmer and promgrammed a sensor for a Vauxhall Astra GT, fitted it to the wheel rim and fitted the new tyre. I then replaced the rear tyre on the other side of the vehicle, but I still had the problem of the vehicle reading the wrong TPMS sensors. What was going on?

These now had to be reprogrammed to the vehicle's ECU. To do this you have to go into the menu settings on the dashboard and scroll down until you find "relearn tyre pressure sensors". Then click on this setting and the horn will beep twice. You then go to the nearside front tyre with your I Sensor programmer and go to diagnose sensor. The horn will beep once, continue to the nearside rear and repeat the process until the horn beeps once. This process is then continued until all wheels are done. Once this process is complete start the vehicle and check that all the tyre pressures are now showing on the menu screen.

I completed this process and test drove the vehicle. Another happy customer!
