BodybyFisher Posted October 25, 2010 Report Share Posted October 25, 2010 Thanks Steve, after a couple of days when the car is warmed up, smell around and see if you smell coolant, that should be gone. Also report to us your temperature readings in traffic, on the highway at highway speeds, etc Good job, glad we could help, you saved a lot of money and learned a ton Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

BodybyFisher Posted October 25, 2010 Report Share Posted October 25, 2010 did you disconnect the battery during your work? If not disconnect the battery and let the system go through a relearn, you cleaned out a lot and the systems need to do a relearn Did you remove the ISC motor and the TPS from the throttle body? Does the TPS have an adjustment on your year, if you removed it?, I think on your year the TPS is adjustable but I am not 100% sure Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

BodybyFisher Posted October 25, 2010 Report Share Posted October 25, 2010 When your engine light comes on, it means that you set a code, extract your DTC codes by pressing OFF and WARMER and post them here Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

steveo412 Posted October 26, 2010 Author Report Share Posted October 26, 2010 •A failed camshaft position sensor will show up in a number of ways. The worst-case scenario is that there is no spark in the combustion chamber. Other symptoms can include excessively long cranking time when starting cold, rough running on an intermittent basis, poor idle, stumbling or hesitation, a drop in mileage and stalling upon acceleration. These symptoms may also be caused by a failure in the wiring of the sensor. ,,,thats exactly whats happening,,got the wires wrong,,can u see if u can find the colors for me,, Link to comment Share on other sites More sharing options...
BodybyFisher Posted October 26, 2010 Report Share Posted October 26, 2010 You didnt rewire the camshaft sensor, you rewired the crankshaft sensors no?

BodybyFisher Posted October 26, 2010 Report Share Posted October 26, 2010 there was a total of three clips 2 got pulled out,,the round one stayed in,there under the front exgaust header The camshaft sensor is on the passenger side of the REAR cylinder head, check to see if the sensor wiring got disturbed by moving the heater pipes, the sensor faces the outboard Down by the crank sensors (2), you also have the oil pressure switch, and possibly the oil level sensor that you might have removed.

steveo412 Posted October 26, 2010 Author Report Share Posted October 26, 2010 ok,,that code that came up is that the camshaft sensor? Link to comment Share on other sites More sharing options...
BodybyFisher Posted October 26, 2010 Report Share Posted October 26, 2010 I just looked at my 94 manual P083 is 24X Reference Signal High This checks for 24X signal at a logic high condition. The fault could be induced by the failure of either crankshaft position A or B sensor input signal to the ICM This is the correct wiring for the crank sensors Crank Sensor A - A terminal = PPL, B terminal = YEL Crank Sensor B - A terminal = BLU/WHT, B terminal = BLK Now, I am not sure if the top or the bottom is the A sensor, Ill keep looking. DO NOT run the engine again until you verify the wiring.

BodybyFisher Posted October 26, 2010 Report Share Posted October 26, 2010 Make sure that you put back all GROUNDS that came off the front harness, there are a few! OK I found that the A crank sensor is the TOP (in the upper crankcase) and the B is the bottom (in the lower crankcase). Check your wiring for correct A and B terminal wires on each crank sensor and connectors for being snapped on. ALSO, make sure that the wiring did not MELT up against the exhaust manifold Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
BodybyFisher Posted October 26, 2010 Report Share Posted October 26, 2010 ok,,that code that came up is that the camshaft sensor? NO you said this "A failed camshaft position sensor will show up in a number of ways" and you said this for the CODE, po83 came back,,Crankshaft to Ignition Module Failure When the code P083 is 24X Reference Signal High according to the manual. I was following your a failed camshaft position sensor will show up in a number of ways. I am not sure where that came from but this is related to the crank sensors or crank sensor wiring (probably). CLOSELY check your wiring for the A and B terminals, for each crank sensor, Mike Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

CarlaValentine Posted October 26, 2010 Report Share Posted October 26, 2010 As another note, if you had to tape the wiring at all you should be sure to use heat-shrink tubing for a good seal, and I would wrap it in high temp electrical tape...just to be safe. It gets terribly hot under there... Link to comment Share on other sites More sharing options...

BodybyFisher Posted October 26, 2010 Report Share Posted October 26, 2010 nice find mike,,i took photos of the engine before i worked on it,and i see that i put them in the wrong holes,,im gonna change it and see what happens Steve, if you are going to learn anything from this thread, PLEASE be more detailed and try to be clear. I just found this post above I must have missed it. What did this mean, "I put them in the wrong holes"? The crank sensors? When you wired the new connectors on to the crank sensor leads, did the pigtails on the new connectors have the proper colors on them or was the wiring just black? Did you pay attention to the A and B terminals on each connector, when connecting the wires, were the A and B terminals clearly marked? If not, I have the connector END VIEWS in the manual Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
steveo412 Posted October 26, 2010 Author Report Share Posted October 26, 2010 im very sorry mike,,im very frustrated ,now when i got them pigtails yes they were black,to be truthfull i just wired them in ,,not paying attention to what i was doin!yes the old one and the new pigtail have a and b marked,with everything u gave me,,i will do it right,,and yes thay may be in the wrong holes,i will check that 2, Link to comment Share on other sites More sharing options...
BodybyFisher Posted October 26, 2010 Report Share Posted October 26, 2010 OH GOOD! At least we know WHY the car is not running. I am surprised it ran at all, I hope no damage was done to the crank sensors or the PCM or the ICM I thought that the dealer gave you the color scheme? Anyway, you are learning, huh?
