: New Throttle Body??? Please help!! Anyone??

The day after Thanksgiving my '92 9000 CD Turbo wouldn't start and just yesterday the Saab dealer told me I need a new --Throttle Body, Throttle Body Controller, And Pedal Switch and that it is going to cost me $2200.00. This is more than I can afford! Do I really need to replace all three of these components? How much could I reasonably expect to pay? The Saab dealer said they are easy to replace (only three hours) but that the parts from Saab are expensive. Please help! Anyone!!! :o

Hi, carrieday. Welcome to SaabCentral.
My first thought is why would they need to change all three components? Surely they can't all have failed at the same time? I'm not saying they're trying to rip you off, but it's not unknown for dealers to simply replace everything rather than try to diagnose the fault.

I assume your CD turbo is a 2.3, and I think traction control reached the US by '92 so it wouldn't surprise me if they had to change the throttle body. This was revised in later years to improve reliability. You may be aware that 9000s with traction control had an electronically-operated throttle ("drive-by-wire"). I know that gold-plated connectors were one of the improvements so perhaps they want to replace all the components with new ones with the better connectors. I thought this only affected the throttle body, though.

Did you have any problems with the car before this? It is not uncommon for earlier traction-control models to go into limp-home mode when they fail. i.e. the accelerator pedal gets heavy, it won't idle properly so you have to keep your foot on the accelerator to keep the engine running and all the control of the accelerator is near the bottom of the pedal travel. The orange "TCS" light will be on when this happens.

When you say the car wouldn't start, would it not turn on the starter or would it turn but not fire? Or would it fire, but not keep running?

Answering a question with a load of other questions, I know, but to know whether the dealer is right or wrong, we need to try to diagnose the problem for ourselves.

The car started accelerating a little poorly the day before it wouldn't start any more. The engine cranks but it will not start and the car does have the tcs system but the light is not on. I just can't afford 2200.00 right now and I can't imagine why they would have to replace every thing at once. What should I expect? The only other thing I have had to replace was a "ignition cassette"? about a year ago. Thanks for any help or suggestions you can offer

Hi Carrieday,

Sounds like an "interesting" problem. What you can do, if you know anyone localy to you with a 9000, is to start swapping things about. Start with th DI and work through.

If that's not possible then you could find another Saab specialist and get them to look at it. But it dose sound strainge to have to replace everything...

I had a dodgy throttle problem with my old car (b4 I got the Saab), it would start some times and others not. luckily it was the same model as my Dad's so I started to swap bits around and found it was the potentiometer on the throtle body.

Anyway good luck.

Just been looking on the net and if you want some idea of cost for parts (I think your in the USA) look at http://www.eeuroparts.com/ and put in your car details and look under "Engine Electrical".

e.g
Throttle body assembly $650 aprox
Throttle position sensor $50 aprox

Replacing the stuff is not too tricky, just need a spanner or two and a workshop manual.

Thank you everyone for your replies, they have been helping a lot. I got the codes from the dealer for the three parts they want to replace- 78390 for the throttle body control unit, 25771 for the pedal switch, and 22220 for the throttle body itself. I spoke with another mechanic, and he seemed to think, from those codes, that it is simply a short in the control system. I took my car from the dealer a couple of days ago- it started up perfectly, and drove with no problem to my house two miles away. The "TCS" light was off. If the all three of those parts are supposedly bad, would it run so easily off and on? After research, I feel confident I can change the parts myself for much less than the dealer wants, but if it's a short, well, I just don't know. Still searching for more possible solutions.

78390 is "throttle control faulty"

22220 is "no +30 pin 22, intermittent", which I think relates to the controller. For cars with VIN numbers before M1016012, there is a Saab bulletin about changing the throttle control module.

I can't find a description for fault code 25771.

Sorry I can't help more - I'm not familiar with the TCS system.

As an engineer (not in the automotive industry), I am inclined to think that there is most likely a single underlying problem.
