#771 of 1436 Re: Having some issues with my 01 Cadillac Catera... HELP!! [az_hvy]

I had the same issue with my 2000 Catera. ABS, Engine Light all on and the Speedometer was working sporadic. I did allot of research and thought it was the Electronic Break Control Unit. The dealer wanted $1400 for the part, so I did my homework and found a site called - www.bba-reman.com. I had my own shop remove the module, I sent it to BBA, and they tested (It was bad) fixed and returned to me all for $150.00. My Shop installed and I am happy to say that the problem is GONE!
#772 of 1436 small vacuum leak, intake plenum hose
Sep 08, 2008 (9:18 am)
Does anyone know what vacuum line goes to the small 90 degree hose that is on the underside of the intake plenum. Its on the driver side. About a 1/8" ID.
After having a tune up done, I kept hearing a small hissing. Found it to be this little hose, BUT there is no plastic line going to it.

Personally, I would go back to whoever did the tune-up and have them fix it. But then again they may just plug it up. Is it toward the front of the engine or back toward the firewall. Have you checked all vacuum operated items inside the vehicle like AC/Heat (blows from proper ports as adjusted)etc etc?? Does vehicle run rough or idle rough?

I have a 2000 Catera Sport and I think I am having a similiar problem. I have oil in my coolant overflow tank, but NO coolant in my oil. My first fear is that I had a blown head gasket, but my mechanic tested for that and I am fine. He is not familiar with my car so I have to do my own research. I can think of no other source of oil in coolant that the OIL COOLER. Can anyone think of any other source before I purschase the oil cooler kit?

Is it motor oil or transmission fluid? That is the only difference I can think of. If trans fluid, it is the trans fluid cooler in the radiator. If motor oil, then it is the engine oil cooler under the intake manifold.

When I bought my 98 the check engine, ABS and the TC light stayed on also the speedometer didn't work The code i got was DCT P0501 ( Speed Sensor Circuit) bottom line is it was the EBTCM ( Electronic Brake Traction Control Modulator) Dealer wanted over a grand to fix it. Below is an address of a place that will rebuild it for 250 (I had a 5 day turn around via UPS) and I found a great shop here in Phx that pulled the codes removed and replaced it and reset comp for about 250 so 500 total
You can still drive the car while it is off if you make sure the housing is covered and kept dry(piece of plastic, shop rag, and duct tape)
Good Luck and let us know
#778 of 1436 Engine Wiring Harness
Sep 13, 2008 (8:24 am)
Recently, My 01' Catera has been shutting off whenever the car was running. i took it to the local GM dealership and they told me that the wiring harness had an open circuit in it some where. They also informed me that whenever they shook the harness the car would shut off. Could anyone tell me what circuit in the engine harness would cause the engine to shut down like this.

A common problem is the Crankshaft Position Sensor. It runs from the senor to the wire harness, and runs along the oil cooler lines. The wire tends to get really hot, and cause intermittent failures before going out completely. The ECM needs this sensor to know when to fire the spark plugs and fuel injectors.
#780 of 1436 ah ha.... could be new evidence....
Sep 13, 2008 (9:30 am)
Could this be further evidence that the wire to the cps has goten hot along the way and when it gets "HOT" it tends to contract and causes an open circuit then it cools and re seats itself........ the same could be emulated by wiggling the wires.... what do ya'all think,? Lee...
