Oil pressure is very important in vehicles. If your sensor is bad or reacting to an engine problem, it is best to take it to a professional to get it checked. without proper oil pressure you could seize up your engine.Will a code P1189 cause my alero to crank over without starting
You can try to unplug the oil pressure sensor wire that provides oil pressure info to the ECM, if the oil pressure is to low it should keep the engine in the V 8 mode all the time. That said it may send warning's to other computer sensors and cause havoc, but it might work. computers ?
No. But you may be out of gas and not know it.
no iat measures intake air temp maf measures amount of air (volume) so pcm knows how much fuel to keep proper fuel mixture
No. The harmonic balancer does exactly what it says. It is to keep the engine from viberating. You need to install a manual oil pressure gauge and run the engine cold and hot to determine if you really have a pressure problem. Most likely you have a bad oil pressure sending unit.
To keep the coolant from boiling, just like the old pressure cookers your grand parents used to use.
I have seen a faulty boost sensor keep the turbo from "kicking in" but it didn't stop the engine from starting.
Oil pressure is low, oil pressure sensor has failedOil pressure is low, oil pressure sensor has failed
No there is not a sensor to keep it from starting if the oil is low
Yes it could
yes the map sensor will keep the car from running.map stands for manifold air pressure and if the ecu cant get a reading it will not start and run.
No I would not expect low oil pressure to keep the engine from starting. Depending on how low the pressure is it might not be a good idea to run the engine much until the low oil pressure problem is corrected. Since there is no gauge built in on that year Celebrity I assume that the oil pressure light is on. Low oil pressure can be caused by a number of problems including failing oil pump, clogged oil filter, low on oil or loose bearings as well as a failing oil pressure sensor. When the pressure sensor fails it tends to show low oil pressure and if that is the cause then replacing the sensor can fix the problem. If it were my car I would first hook up an oil pressure gauge and find out what the pressure is before I attempted to fix the problem. Pressure should be at least 30 psi.
A throttle position sensor might keep the engine from starting. Any number of things can cause a vehicle not to start. The starter and the gas line sensors are also a possible culprit.
From a cold start, yes it can.
It sure will if it's bad.
Nope. The computer doesn't even look at the oxygen sensor until the oxygen sensor reaches operating temperature.
It could, depending on make, model and year.
