Can a bad O2 sensor cause a misfire in one cylinder?
In reviewing this answer, a formerly common situation (carburetor or throttle body injection cars) in pre-OBD2 cars, a bad or carbon fouled O2 sensor would drive the system rich, and could foul a specific spark plug causing a misfire in a single cylinder.
What sensor is used to detect engine misfire?
crankshaft position sensor
The OBD II system detects misfires on most vehicles by monitoring variations in the speed of the crankshaft through the crankshaft position sensor. A single misfire will cause a subtle change in the speed of the crank.
Can I drive my car with a bad cylinder?
It is not advisable to be driving any vehicle with a misfiring cylinder as this can cause irreparable damage to the engine of the car. The most common cause of a cylinder misfire is bad spark plugs or the imbalance of air or fuel mixture. Note that driving with a misfiring cylinder causes a major power loss in the car.
How do I know if I need a new cylinder head?
Engine overheating Since the cylinder head gasket also seals in the coolant and oil, you may see streaks of oil and coolant streaming down from the gasket. You may also notice a loss of engine power due to lower cylinder compression if the head gasket leaks to adjacent cylinders.
What causes a cylinder to have a misfire code?
When you have a misfire code for a particular cylinder, you can focus on one of three things: an ignition problem, a fuel injector problem or a compression problem. Every time a spark plug fires, the spark burns a few molecules of metal off the plug’s electrodes.
Can a bad cam sensor cause only one cylinder to misfire?
Answer: If the faulty cam sensor has a bad effect on ignition timing (at least in some models), it can lead to a misfire; enough raw fuel will cause the catalytic to get red hot. Question: Would a bad camshaft sensor cause only one cylinder to misfire?
What can cause an OBD-2 engine to misfire?
On OBD-II cars, the OBD-II system will not only identify misfires, but also coil and injector problems. Consequently, if the (MIL) lamp is on and you find a code for a misfiring cylinder; and a second code indicating an injector fault for the same cylinder; bingo, the engine probably has a bad fuel injector.
What happens when one cylinder is not firing?
When one cylinder is not firing correctly, the engine will become unbalanced, and this can cause heavy vibrations inside your cabin on acceleration or at idle. 4. Check Engine Light Modern cars have great monitoring for all the different car sensors on the engine.
