Will a bad knock sensor stop a Volvo 240 from starting?
I have a 240 and with the knock sensor unplugged it will still start so I would have to say no.
Will the knock sensor cause the car not to start?
No it will not. The knock sensor is used to adjust the timing.
Any way to temporarily repair plug for Knock sensor on 1993 Chevy blazer k1500 to get it to start to get it home?
You have another problem other then the knock sensor if the engine will not start and run. A knock sensor will not cause the engine not to run.
What are the two sensors on the driverside of the engine in 83 Volvo dl?
One is the Head Temp sensor, other is either a knock sensor, or on the throttle body it's the cold start injector
Could a bad knock sensor cause your car not to start?
No all it is is basically a microphone to monitor for noise-nothing to do with the engine running.
Will a knock sensor start working correctly if you start using a high octane fuel?
Perhaps--unless the sensor itself is bad.
1991 Volvo 780 ran hot top hose burst temp sensor shorted after replacing hose and sensor car wont start only thing moved was knock sensor plug and temp sensor plug?
Run a compression test. Unfortunately Volvo engines are among the group that are sensitive to overheating. I wouldn't waste any more time on it until you've verified that the compression is up in all cylinders.
Would code 43 electronic spark control failure cause the vehicle to not start and would replacing the knock sensor fix this or is it an ECM issue?
I have a 1990 Pontiac Safari wagon that would not start,after much testing we found one bad fuel injector replaced it and car started but ran terrible, did more testing and found bad ignition module, replaced module runs better but now have code #43 knock sensor and engine is running in default mode switched ECM no help must be knock sensor don't think knock sensor would keep car from starting but the other things mentioned here would. Hope this helps. This wagon has 3.1 engine. Havent changed knock sensor yet.
Can a bad knock sensor cause the car do start bad?
A knock sensor assures that you're getting as much power and fuel economy as is possible from your engine. More details: A knock sensor allows the engine to run with the ignition timing as far advanced as possible. The computer will continue to advance the timing until the knock sensor detects pinging. At that point the computer retards the ignition timing just enough for the pinging to stop. The knock sensor responds to spark knock caused by Pre-detonation of the Air/Fuel mixture. As the flame front moves out from the spark plug ignition point, pressure waves in the chamber crash into the piston or cylinder walls resulting in a sound known as a knock or ping. This is caused by using a fuel with a low octane rating, overheating, or over advanced timing. Sometimes it can be caused by hot carbon deposits on the piston or cylinder head that raise compression. A knock sensor is comprised of Piezoelectric materials; Crystals that when impacted, generate a voltage (same idea as a BBQ ignitor). This voltage is monitored by the computer, and when an irregularity is detected, the computer corrects timing in VVT (variable valve timing) engines, or triggers a DTC Diagnostic Trouble Code) in older vehicles.
Are there sensors that would cause a 1997 dodge stratus to not start?
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.
Will a speed sensor cause car not to start?
cam or crank sensor
Can a bad crankshaft sensor cause a2.3ford not to crank?
A bad crankshaft sensor on a 2.3 Ford may cause the car to not start. A bad crankshaft sensor can crank, just not start.
