Set Condition
WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
When fault P2135 is active, the Powertrain Control Module (PCM) looks at the difference between calculated MAP based on TPS 1 input and sensed MAP. The same is done for TPS 2. If the PCM determines that the TPS 1 error is larger than the TPS 2 error, this fault is set. ETC light will illuminate.
