Engine Performance problem
1999 Chevy Silverado 6 cyl Four Wheel Drive Automatic 113000 miles
Put on machine and came back with P1345 code. I checked the voltage input at the crank sensor and got 12 volts, output voltage was 2.5 volts.
Input voltage at the cam sensor was 12 volts, output voltage was steadily fluctuating up and down the scale from approx. 10 volts to 2.5 volts.
My question is whether this voltage is correct and there is no problem with the sensors, or are one or both faulty maybe.
Truck has had new plugs, wires, air filter and oil change but has like a misfire while driving about 75 % of the time any ideas?
have the same problem?
