When mine would go, the engine would all of sudden stop running. Like if you were trying to compression start a standard engine. Only it happen to me when I was doing 80 kph. The it would start again. For some people, once it occurred the engine will never start. Ford did eventually put out a recall on them but that was a long time ago. The I went to have things repaired had told me that there is no real indication when they will fail. In fact, they had installed a new sensor into a truck and the next day the sensor failed. So until it fails just keep driving it.

∙ 13y agoIf the cam position sensor goes bad certain vehicles may not start (some require a signal from this sensor before they will). If it does start it will run rough especially at low revs. Most ecu's will give you an error code if the cam position sensor goes bad. They can be tested with an oscillating volt meter ( oscilliscope ) by checking the signal wire and ground while someone else cranks the starter. Many times these sensors are working fine but need to be cleaned to give a proper signal.

Can the crank position sensor be bad even though it checks out good with an OHM meter?
Yes, but not usually. If the computer is telling you that you have a bad crank position sensor, it could also be a connector or damaged wire. Don't be too literal.
Does a knock sensor ECM error mean that sensor is bad or that the sensor is just reporting a knock in the engine?
The sensor is bad. A properly-functioning knock sensor allows the ECM to advance timing until it senses a knock. It then retards timing until the knock just barely goes away allowing for optimal gas mileage.
Will a bad crankshaft positioning sensor prevent spark to spark plugs?
Yes it can. The crankshaft position sensor is one of the major sensors for spark timing.
What happens when the cam shaft goes bad?

What happens when the crankshaft position sensor on a 93 Ford Taurus sho goes bad?
car will not start up
What happens when the throttle position sensor is bad?
When Throttle Position sensor is bad when you step on pedal and it does not move, engine light is on!
What happens to a 1999 Honda Accord when the oxygen sensor goes bad?
When the oxygen sensor goes bad, the check engine light goes on.
What happens to a car when its intake air sensor goes bad?
It breaks.
What happens when the crankshaft sensor goes bad?
If the sensor is erratic, then the engine could shake or sometimes not run. If the sensor is completely bad, then the car wont start at all.
What happens when cam sensor goes bad in a 1999 Saturn sl2?
Nothing...........there is none.
What happens if the oxygen sensor goes bad?
The check engine light will illuminate. The code(s) will direct you to the faulty sensor.
What happens when a oxygen sensor goes bad?
When an oxygen sensor goes bad a car will burn gas at a higher than normal rate because it will not be producing as much power as before. The oxygen sensor checks the amount of exhaust.
What happens when an o2 sensor goes bad?
When an O2 sensor is bad your car will not run efficiently. You will use more gas than you would normally use on a trip.
What happens when crankshaft sensor on 2001 Dodge pickup goes bad?
AN engine that will not run correctly if at all.
