What happens if you don’t calibrate TPS?
If your TPS is faulty or uncalibrated, the sensor will be unable to accurately determine the position of the sensor. This will lead to a variety of symptoms, all of which are caused by the fact that the ECM is delivering the wrong air/fuel ratio to the cylinders thanks to the bad sensor.
What does the p0122 code on the throttle position sensor mean?
Throttle Pedal Position Sensor/Switch (TPS) A Circuit Low Input What Does Code P0122 Mean? Code P0122 is triggered when your vehicle’s Engine Control Module (ECM) detects that your Throttle Position Sensor (TPS) circuit A is reporting an output voltage that is below its expected voltage.
What causes error code p0122 on the ECM?
Code P0122 is triggered when your vehicle’s Engine Control Module (ECM) detects that your Throttle Position Sensor (TPS) circuit A is reporting an output voltage that is below its expected voltage.
How to troubleshoot a p0122 trouble code on a Dodge Ram?
Testing to see if the throttle position sensor is bad (or not) is the way to troubleshoot and repair a P0122 trouble code. The TPS signal voltage increases/decreases as the throttle plate opens/closes (and is not stuck producing a low voltage value).
