2002 Chevy Impala 6 cyl Front Wheel Drive Automatic 94000 miles
I'm getting a PO336 code " Crankshaft Position Sensor circuit, range of performance problem.
There are two sensors in the model. 24x in the front and the other one in the block on the back. I performed a voltage check on the 24x. It is supposed to be 12 volts. I only get 11.05 volts. Is this the problem causing the code? Also, I'm not sure how to check the rest of the circuit.
Also, I get a tiny hesitation while accelerating and then again when I settle in at any top speed like 55mph or 60mph. I figure this is because of the PO336. Is there somthing else that could be going on that is causing the code?
