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
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.
crankshaft position censor
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
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.
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.
An intermittent crankshaft sensor will not let the engine fire the correct times. This can definitely cause a misfire for the engine.
i just farted,how can i stop farting cause it smells like egg salad sometimes
temperature gauge not working can be caused by a bad temp sensor in engine, a bad gauge in dash, or a bad fuse
Yes, an unplugged sensor can cause a check engine light.
A bad crankshaft position sensor on your Chrysler 300 will cause the engine to run very rough or not run at all. The malfunctioning sensor can cause damage to your engine, if not repaired.
There are more possibilities than the mind can imagine.Take it to a repair shop and have them inspect the underside. It could be the engine mounts, they might need replacing, check them first.
If the AC is on constantly, the fan will be on constantly. If that's not it, it mught be the fan relay or the temperature sensor.
No it will not.
It sure can.
There are a couple of things that can cause your Pontiac antilock brakes to lock up. The most common cause is a malfunctioning ABS sensor.
There is no distributor on a 99, so there are a few sensors that can cause this. If you've had your intake replaced, or it is leaking, it could be the Cam sensor, which is located on the top of the engine, under the power steering pump, there is also a crank sensor (Is your tachometer working?) and lastly there is the ignition module which is located under the coil packs on the back of the engine.
degradation of the coolant. flush the system and refill it, and all should be well.
depends if it is bad it can but are u actually talking about the o2 senser or the mass air flow sensor on the intake.... cause it can be a bunch of things but the air mass flow sense is easy to replace i have to buy one and the tools to replace it and the sensor is 45 dollars for my 97 Pontiac Bonneville se v6 3.8l hopefully that fixes the probem with it not wanting to start ...i got fuel pressure it just isnt fireing
A bad engine temp sensor can do that.
Not likely. A bad O2 sensor would illuminate the check engine light and the engine performance would suffer.
water temp sensor wire grounding out could cause this problem.
