CID trouble

[V6Hova]

I recently purchased a 95 MTX, so I'm new to the sho crowd. Since then the car has been one continuous headache. The CEL would come on and the car would buck real bad. Since then I've replaced the ignition coil, plugs & wires, CPS, and TB, etc. Now it runs rough at idle and periodically CEL still comes on, tach goes to zero and sometimes the car won't even start. I Checked the fuel pressure and I'm getting 30 psi at idle. I just checked the codes and came up with a 214 (CID) and a 542 (fuel pump secondary failure???) Can anyone give me any insight on this before I lose any more hair?

Sorry to hear about your sho giving you a hard time I think its safe to say most of us have been there,unfotunately when these cars run right they run great and it all seems worth it somehow.
Anyways I don't know about your 542 code, but the CID is causing your tach problems hard starts and on the occasional times when you get the car to runbut the tach still doesnt work, the rough idle,also it at least has something to do w/ the CE light. Good news though is that it's only 24.99 at Auto zone and is pretty easy to get at. Its located near the passenger side of the motor by the firewall and to the upper left of the serpentine its got 4 ( I think ) wires going to it and 2 small hex screws holding it in. Somewhere in the archives there is a picture post. I had to use a "sidewinder" ratchet and remove the battery but I like to make as much room as possible to work. Just be careful not to loose those little screws into the pulley system,the new CID doesnt come w/ them!
Good luck
Steve

Just as an FYI those bolts were 5.5 mm on my SHO. Kinda a werid size.

Search keys: CID location 214 Wells F134

The cylinder identification (CID) sensor is located on the passenger side end of the firewall side exhaust camshaft (right or rear cylinder bank). This device is used by the engine control computer (EEC) to identify where the number one cylinder is at startup so that it can synchronize the sequential port fuel injection and the distributorless ignition systems.

If it is not providing a signal to the EEC, the engine will start, but in a very ugly, sometimes bucking or backfiring way because the EEC was guessing at the location of the cylinder. Once the engine is running, the tachometer, which gets its signal from this sensor (and the crankshaft position sensor, CPS or CKP), may drop to zero or a fraction of the proper engine speed. With the symptoms you described and the fact that you received a 214 code confirms that the CID sensor is not funcitoning properly.

The CID sensor is located in the center of the first photo below, just to the left of the upper timing belt cover. The second photo shows the sensor with the timing belt cover, timing belt, camshaft pulley and rear metal timing belt cover removed (not required to replace the CID alone). Those two 5.5mm screws can also be removed with a more common 7/32" socket. Use a 1/4" socket driver and you may have to remove the power steering fluid reservoir up and out of the way (hoses still attached - tie wrap to the hood strut) for access. The electrical connector is removed by squeezing the latching clip inward toward the connector while pulling the connector away from the sensor.

Some possible sources of the sensor are given here:
Wells F134, AutoZone $32.99
Motorcraft DU47, O'Reilly $40.99
Borg-Warner CSS29, O'Reilly $27.99

One thing can be said about the SHO crowd is that you guys are extremely knowledgeable and very helpful. I just installed the new Cam Position sensor. And so far NO CEL. So thanks guys.
