Hello, I have the fault code P2033 I have tested with the multimeter to see the resistance of the Exhaust temperature gas sensor according to google reading should be between 50-150 but mine was showi … read more

A faulty ECT sensor can send a false signal to the onboard computer, resulting in an incorrect air-fuel mixture. For example, a faulty sensor can send a signal indicating the engine is cold when it is not, and more fuel will heat the engine quickly. This will cause the fuel economy to drop and decrease the engine’s performance. 3.

There are several other symptoms of a bad crankshaft position sensor. Crankshaft position sensor symptoms include the following: 1. Difficulty Starting the Vehicle. One of the most common symptoms, if not the most common, of a failing or bad crankshaft position sensor, is the problem with starting the vehicle.

The PCM uses the "B" Camshaft Position Sensor to tell it when the Crankshaft Sensor signal is correct, when a given Crankshaft Position Sensor signal is timed to Cylinder #1 for timing, and it is also used for fuel injector synchronization / start of injection. Codes P0365 or P0366 may also be present at the same time as the P0368.

With the engine running, the PCM constantly compares input signals from the CKP and CMP sensors. If CKP input signal voltage is lower than expected under certain circumstances, a P0337 code will be stored and a MIL may be illuminated. Other crankshaft position sensor trouble codes include P0335, P0336, P0338, and P0339.
