Why are all my sensors dying???

[thumper_svx]

Anyone got any input here? All my sensors in my car appear to be dying and I can't seem to get them fixed. The Crank Position Sensor was the first, then the O2 sensor. I replaced both Crank Position Sensors but the problem code never went away. Had some other problems that went away... now I dowloaded the logs from the last month and was amazed to find the O2 sensor to be a problem again (not sure which one), but now I've also got a camshaft position sensor problem and a problem with a coil!!!

Here's the raw data from my download. Does this look like a valid set of problems, or could I be looking at my OBDII system just self-destructing? Input anyone?

[huck369]

I'd check for some bad grounds on the motor....as they can cause the same codes....

[Mr. Pockets]

Yeah, I agree with Huck - bad grounds or even bad connectors, maybe? I don't have enough experience with the wiring harnesses to say what wires go through what connectors with what other wires, but could a compromised connector cause errors like this? Maybe stripped insulation somewhere?

[Beav]

Normally if we find a run of more than one or two sensors throwing codes we begin to take a good look at the ECU. I'm never one to scream 'computer' without a lot of investigation, but your list looks a bit suspicious. Maybe someone will loan you one to try.

[thumper_svx]

Yeah, both the grounds and the ECU were my suspicions also.

First; the simple one. Where are the main grounds in the engine bay? I intend to go through at the weekend and see what's loose or broken.

Second; anyone got an ECU from a 1996 or 1997 car that they can loan me for a week or so? I'll cover any necessary shipping!

[Earthworm]

How's your battery?

My Justy started throwing multiple codes but it turned out my battery was dead.
