You may have seen the problems I had with two corroded Tire Pressure Monitoring System (TPMS) valves and the amount that was involved in repairing them.
If you have read that post you’ll be aware of the grief the tyre fitter had trying to get one of the valves out – due simply to the level of corrosion.
Around four weeks after the repair, the EVIC on my Nitro suddenly started showing that one of the wheels was “missing”.
Now it’s possible than the sheer amount of shock the sensor received caused some damage, the other possibility was that the battery in the sensor had simply run out.
One other option for this “missing” wheel was that the receiver in the wheel arch was at fault. Swapping the front wheel with the rear wheel confirmed it was a sensor issue as the missing wheel moved to the back and the front one re-appeared!
So armed with that confirmation I went back to The Tyre Sensor Shop and bought a replacement sensor. The part number was 65722-67.
Having paid just £41 quid I was expecting a pattern part to arrive in the post. I was pleasantly surprised when a genuine Schrader sensor arrived.
The sensor was upgraded recently so it looks different from the OEM one.
It still transmits on 433Mhz though so it’ll work fine.
These sensors do NOT need programming for the Dodge Nitro. Even though each sensor has its own electronic identifier in the form of a unique ID code they all transmit the exact same type information on the exact same frequency. To work out what signals it is receiving the Dodge Nitro has three receivers, one in each wheel arch and these are used to read the signals from the sensors. The forth wheel arch doesn’t need a receiver as a simple process of elimination is used to work out the position of the remaining sensor.
Here’s how the old sensor looks.
Once fitted, the TPMS continued to show a “missing” wheel, despite the car being driven around the ATS car park for a few minutes.
Not to worry though, within five minutes of driving at 30mph the TPMS had worked out what was what and the wheel re-appeared on the EVIC display.
