Car: 1988 trans am Engine: 305tpi Transmission: 700r4 | TPS voltage
| I read a past post about testing your knock sensor. Key on wire off makes 5 volts.Wire on sensor,probe back of plug and should be about 2.5 volts. Mine shows 9 volts on both sides of the test. It just started having intermitent knock problems and shows the ESC code. It is the original at 120000 miles,its a 86 305 TPI.Does this sound like a problem with voltage to anyone?? Thanks Allan | | | |
