#977 of 1436 Please help Check Engine light on and all these codes came up
Mar 04, 2009 (5:51 am)
I have a 2000 Cadillac Catera, purchase it last year for $3900 and have had problems ever since. I have already spent a good 600 or more on it. The car looks immaculate inside and out, only has 64K miles but its been a nightmare. It currently has no AC, the back window is broken comes down and wont go back up and now the Check Engine Light stays on...I took it to Auto Zone this morning and they plugged it up...It has the following codes, PO155 Oxygen sensor bank 2 sensor1, PO305 Cylinder 5 Misfire, PO 135 Oxygen Sensor Bank one sensor 1, PO141 Oxygen Sensor Bank 1 sensor 1, PO100 Map sensor Circuit A malfunction, PO1161 Manufacturing control fuel air mentoring and then P1141 I have no idea which one that is. I am currently divorce, the ex is out of state and I have no dang clue what to do with this thing and am too broke to go to the mechanic. Any idea what Im looking at, any idea what that may cost me? I want to sell the car and at least get the what I spent (doubt it) but I do not want to sell someone a bad car. Please guide me....desperately seeking answers. Thank you all and God Bless!

The no-brainer el cheapo first thing to check is the gas cap. Not tightening the gas cap will cause the engine light to go on. When engine light first camer on I immediately drove 45 minutes to the dealer only to discover that I had no screwed the gas cap on completely tight. When I "bumped" into fellow Catera owners after first getting car and would ask each to compare notes. Unanimous that everybody loved driving the Catera and would add "be advised that the engine light will come on if you don't completely tighten the gas cap".
Also could be a broken gas cap if persists after tightening. Wasn't the case with my Catera but with 2004 Saturn Vue had to replace defective gas cap.

Check air cleaner, sometimes one little thing will cause a bunch of probs. I'm not as good at these Catera probs. as some others but am learning, be patient these cars are built like a brick shithouse and need to be driven hard I think. The same cars under the Opel nameplate in Germany were used for Police cars. Built for the autobahn if you know what I mean. I've had several oddball cars and this is the best. I think GM copied many of the design features of this car. The similar CTS Cad. replaced the Catera. The window may due to not being used, check switch in console, sometimes spills will cause poor contact. WD-40 is safe for electrical, won't hurt to spray a little on switch. Worked miracles for my old Mercedes.
Water Displacement formula 40 was engineered for drying rocket fuel and was accidently discovered to have other commercial uses. Good Luck! Dave

Have you had a tune up lately? First of all if a cadi engine gets dirty expecially the sensors the check engine light will come on. You need to get the oil changed, get a new air filter put in and make sure the engine doesn't have oil all over it. Cateras have a bad habit of the gaskets getting worn out around 40000 miles. If you have 60 on it you probably have at least one valve cover gasket worn out. Cateras are tempermental. Great when they run well. I would just go to the car wash, leave the engine running and spray the engine with hot soapy water. make sure engine is not extremely hot, then get an undercarriage wash at the car wash. Change your oil that is cheap enough and put in a new air filter. A check engine light is usually something to worry about but on a catera they come on a lot. I have a 2000 also and it comes on and goes off. I know I need a valve cover gasket changed. And yes the gas cap can cause the light to come on but when you ran the diagnostic at auto zone it told you sensors. Clean it up see what happens from there.

I would clean the Mass Air Sensor, its about $6 for a can of CDC cleaner. If its bad it would cost $150. Then if you can describe what the car is doing, it might well be the Crank Sensor an $65 part. The AC should be rather easy to see if you either have a leak, electrical issues, and or a bad compressor at worse. The window is an easy fix. Grab it from both sides, inside and outside and shut it. Those back windows are prone to having the cable snap or getting off the track. Its not worth fixing or using. I disagree that the car needs or has seals leaking. Doesn't have enough miles to have these issues. You can fix it yourself or get taken/had by the dealership. I have a 3001 and it has 90,000 miles and its a fine car, if you repair it yourself.

My brother in law is a Mr Good wrench and fortunately he was trained to work on this type of euro car. My father in law owned the dealership. Most dealers failed to train or limited training on Catera's. Its real simplistic and most of the problems are common on 2000 and 2001 Catera's. However, I'm amazed at the needless work done by those who are untrained and or unqualified to work on these cars. Yeah, there are lots of false codes as with most cars these days. But the majority of the stuff is cheap to fix, until you get to the major PM which is the timing belt at 100,000 and its expensive in that lots of stuff is replaced then. This Opel twin/Opel Omega is considered a very reliable car in Europe, but then we are an entirely different society. The engineering and quality of supplier parts is first class. From the Recaro seats, Bose sound, and quality of the interior/exterior beats most manufacturers in the 2000's. Currently they were putting a 4/6 cylinder and a VETT eight in these Opel Omega's.

If you have a power sun roof, make sure its in the shut position. The early models were prone to having that drain the battery. If you used it reciently, you may want to disable its fuse if its positioning is the issue.

Mar 04, 2009 (7:33 pm)
Okay, I've got it figured out. The turn signal is bad. It is an LED unit (made in Spain) which will, from what I can ascertain, require replacement of the entire taillight assembly as I see no way to take the one piece assembly apart without a lot of breakage occuring. There is a small circuit board inside the thing that cannot be readily accessed & I wouldn't know what to do to it if I did gain access to it. So junk yard look out I'm on my way.

Thanx for your help the abs control module is the same thing as the EBTCM. What year of a catera is that book for? The tps/throttle position sensor is located on the front of the throttle body where the intake ducts you unplugg it & there are two screws, tps also has a big factor in your tc & tramsmision. I have just described to alldata online instead of buying books. you did help me figure out how I was going to get to the EBTCM thanx for the help. These cars are a bxxxh to work on

alldata is really good, much better than my books which are for a 2000. i know how it is to need information and no where to get it. glad to help a little. i am just a shade tree mechanic but after all these years it is a pretty big tree. I started to work on my car and found out what a mess they are but I have more in it then it is worth and I like it so I will keep it and do the work.
