Check dark blue/white wire from knock sensor to ecm(electronic computer module)
if it is grounded or shorted to ground then code 43(electronic spark control circuit) will be set
Warm car to normal temperature.shut off engine.disconnect knock sensor.turn ignition switch to on position or run position(engine is not running)
check voltage between harness and ground(should be between 4 to 6 volts)
yes-means bad connector or bad sensor
over 6 volts-shorted to voltage or bad ecm
under 4 volts-shorted to ground or bad ecm
Coolant Temperature Sensor
crankshaft position censor
a bad throttle position sensor will cause: transmission shift issues, bucking, jerking, idle surging, engine cuts off, hesitation on take off, surge while cruising down highway. all or part of these symptoms will indicate a bad sensor. not all the time will check engine light be on!! sometime these symptoms will not set a problem code.
I've had a problem with my O2 sensor and air filter causing my 1998 firebird to misfire.
sounds like a motor mount is broken or a transmition mount. have those checked.
I read that bad motor mounts can cause this knocking sound
Yes, just about any sensor on the engine could cause a no start.Yes, just about any sensor on the engine could cause a no start.
the most likely cause is a flat battery and or dirty battery terminals check all electrical connections from battery to starter (hope this helps)
this is normal for this engine, in fact anything short will trip a check engine light. the cause will be a low coolant condition, a thermostat stuck in the open position or a bad coolant sensor. this is normal for this engine, in fact anything short will trip a check engine light. the cause will be a low coolant condition, a thermostat stuck in the open position or a bad coolant sensor.
i just farted,how can i stop farting cause it smells like egg salad sometimes
An intermittent crankshaft sensor will not let the engine fire the correct times. This can definitely cause a misfire for the engine.
Yes, an unplugged sensor can cause a check engine light.
