Hey guys,

So the ECM finally had a code stored in it (Continuous memory) which is 125. From what I could find the best definition for it is:

125 - TP sensor was lower than expected with the MAF/MAP value in the last 80 drive cycles (M)


Does anyone know where to start with the testing or what the common issue would be? The TPS is about 4 years old from memory. The MAF has been cleaned and the MAF's filaments look ok (could be original MAF with 270k, can't remember).

I'm going to check the resistance values for the TPS.

Thanks
