There is a question on Systoms of a bad Pip Sensor.

It is hard to start a car when it is cold, and it seems like it will die if it doesn't start soon.The car runs fine once it warms up.The throttle doesn't seem to be crisp or smooth when I snap it.The service engine light is on and I have a code.Does anyone know how to diagnose a bad sensor?There are tests that can be done to determine if the sensor is bad.

Ford has a fancy name for a camshaft position sensor.Inside the distributor is where it is located.If you have a code 14, the computer will diagnose a bad or failing sensor.99% of the time that code is correct.It's a lot safer to replace the whole distributor than it is to just change the sensor.There are a lot of chances for things to get messed up during the reassembly of the distributor.

When I ran the car again it was hard to start but once it warmed up it ran great and the check engine light didn't come on.Is this an intermittent problem?Is this a common thing with the sensor?I don't want to buy a distributor if it's not the problem.The grounds are good.When the car runs and I turn on the AC, the engine runs rough and sounds like it will die, but I don't turn it off.Any ideas?Is there a test I can take to make sure thePIP is good?

When the car runs, the engine runs rough and sounds like it will die, and I turn off the AC, it runs normal.Any ideas?If the Iiac is working correctly, you should check it.

There is.The computer has already done that for you.The code can be cleared.The code will return if the sensor is bad.The code may have been a glitch that caused it to set before.You can check the signal.To make sure the output of thePIP is clean, you will need an oscilloscope.You can't use a multimeter to test thePIP.You can wait for the sensor to fail.The engine won't start, so you will know when that happens.

I borrowed an old scope and connected it to the module and here are some pics of the waveforms.I think the wave forms are bad.Shouldn't the waves be square?It tells me that the Pip sensor is bad and not producing a good signal.

It looks like a malfunctioning sensor.The wave should be very clean.The engine will run, as there are still 12v peaks at regular intervals, but it will not run correctly as the timing will be affected by faulty detection of TDC.

I thought it could be a bad module causing the signal to be week.quote

The TFIs are notorious for causing issues.Since there aren't any other symptoms usually attributed to faulty TFI modules, I'm skeptical that it would correct this particular issue.

I have a 1990 ford Ranger with a V6 that has a code 14 but I replaced the ICM and thePIP sensor.What could be causing this?
