Chevy CK Pickup Engine Sensors, Relays, Switches

Modern vehicle systems are managed by the powertrain control module, or PCM. This electronic device gets information about engine operation from various sensors. Depending on these input data, the PCM makes certain adjustments, so that all systems perform smoothly and efficiently. If the sensors are faulty and provide invalid signals, the PCM will not be able to control the respective system properly. Each of the engine sensors on your Chevy CK Pickup is responsible for its particular function. Thus, signals from the oxygen sensor and coolant sensor help the engine control system to go into a “closed loop”; the throttle position and MAP sensor help the PCM to balance the fuel mixture properly.

These and many other engine sensors rely, among other things, on a proper work of the electrical system. If the circuit is broken, the sensor will be unable to send data to the PCM. There have been issues with the throttle position sensor on Chevy CK Pickups. The thing is that on some models throttle position sensor circuits are very basic. They comprise a 5-volt reference, a ground, and a signal circuit that are wired from the TPS directly to the electronic control module. Changing the throttle position sensor can be a cure, but more detailed testing may be required.
