Hey everyone, I broke a sensor on the front of the block last night, working on replacing the front bottom motor mount. The sensor is located about 1 inch lower than the oil filter, and then to the left (passenger side) of the oil filter.

It's white plastic, and is connected to a loom that past the timing belt area, and has 1 plug capped off and connected to nothing, and the end of the loom was connected to this sensor. Plugs are white, sensor was white/ceramic.

After I tightened down the motor mounts, I went to crank the motor over thinking is must just be a oil pressure unit. But the car got ignition for 1 sec and then stopped getting fire and just turned over. I noticed than the Check Engine Light was on, so I cleaned up and went to bed. I didn't check to see if a "oil" light was on or if the car even has one (its new to me), I'll check that tonight when I get home. Regardless the CEL is now solid.


On 2nd though, about the car not starting now, I didn't think a oil sensor could do this, which is why I don't just assume this is what the sensor was, however, I suppose, I could have disconnected something when I was lifting the front of the motor (2" or so max), but since it was pivoting on the rear mount (like a clam shell opening, pivoting in the rear), I doubt anything near the firewall could have come undone.

I have to replace the sender regardless, but I would like to buy one before its too late tonight and I have the dealers closed. I called them, and I guess they don't have exploded views anymore, because telling him it was right there near the oil filter did nothing for him, he wanted a part #. (uhmm, the plug is okay, but the sender took a ratchet to it and is in pieces, I can tell its white, and plastic/ceramic, and I seem to remember the plug that connected to it was a single blade connector. And yes, its in front of the block, all to the left of the exhaust, I would say its right behind the oil dipstick tube if you wanted to get a how far left/right on the front of the block it is.


Thanks in advance,

Hunting the various forums for the person that goes, I know exactly what that is its ->..... :)

Is it possible for this when snapped in half, with top half still in plug and other half in motor, to get a CEL? Just curious, as I prepare myself for finding what else I did that I didn't intend to do.

There may still be other sources of the error code. Follow the instructions in the following threads and get the codes from the ECM.

Thanks, that shows it exactly where I am talking. I appreciate it. I'll jump the diagnostic pins and count flashes later tonight.

I have another question, but it has to do with motor mounts that I have 75% changed already.
Will post another thread.

Thanks Again
