What does p0201 mean on an OBD-II vehicle?

What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. P0201 means that the PCM detected a fault in the injector or the wiring to the injector.

What happens when code p0121 is triggered on ECM?

When code P0121 is triggered, your ECM will go into failsafe mode. Depending on the failsafe strategy of your car, this could lead to limited speeds or acceleration. This problem can also cause intermittent knocking and even stalling for your vehicle. In some cases, the car will not be capable of driving to the shop and will need to be towed.

How does the throttle position sensor work on a jeep?

This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Powertrain Control Module ( PCM ). In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the PCM.

How does the p0123 throttle position sensor work?

The TPS sends the throttle position information back to the PCM on this signal wire. When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts. When the PCM sees a voltage that is higher than the normal upper limit, P0123 will set.
