Can a crank position sensor be intermittent?
Intermittent Stalling
Another symptom commonly associated with a problematic crankshaft position sensor is intermittent stalling. If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall.
What happens when a crankshaft sensor doesn’t work?
With a bad crankshaft position sensor, your engine control unit won’t know the correct position of the crankshaft or cylinders. This will cause a delay in the control unit’s ability to sustain the operation and performance of the engine.
What happens if you don’t relearn a crankshaft position sensor?
What happens if you don’t relearn the crankshaft position sensor? Your car won’t start. Or, because the ECU (electronic control unit) has been negatively affected, your normal driving experience will completely change.
What happens when a crankshaft sensor goes bad?
With inaccurate input coming from the crankshaft position sensor, the engine control unit can’t make the adjustments to spark timing and fuel injection as the engine speed increases. Slow or uneven acceleration can result from a lack of accuracy and make it difficult to maintain a constant speed.
Can you drive a car with a bad crankshaft position sensor?
Can I Start the Vehicle with a Bad Crank? If you wonder if it is safe to start your car when the crankshaft goes, the answer is yes if it is the very beginning of the issue.
