P1690: Understanding The Mysterious Fault Code And Its Description
The P1690 fault code relates to the Fuel Injection Pump Crankshaft Position (CKP) circuit.
This code is monitored when the ignition is on and the engine is running. It is stored when there is no signal within specified window parameters and there are no Camshaft Position (CMP) sensor or CKP DTCs present.
In simpler terms, it means that the Fuel Injection Pump CKP sensor does not agree with the ECM CKP sensor. This fault code indicates a discrepancy between the two sensors, which can affect the proper functioning of the fuel injection system. It is important to address this issue promptly to ensure optimal performance and avoid potential engine problems.
