Re: Any guidance on the following codes thrown? (iamnotmad)

oh, also, if no info on the specific codes above, how bad is it to drive in limp mode for a few days until I can get it to the shop (with the CE light on)?

Limp mode shouldn't hurt anything. As long as your CEL doesn't start flashing.<p>If it were me i'd suspect the throttle position sensor. I'd start by getting a diagram of that circuit as well as specs.<p>

Re: (iamnotmad)

Oh Boy now when i start the car it revs up and down as if I were pressing the gas pedal then letting off over and over. And actually pressing the pedal does not seem to do anything. Guess this means i have to get it towed to the shop. What a bummer. <p>Any other suggestions? <p><br>Thanks.

Re: (iamnotmad)

Yup, sounds like the throttle position sensor. <p>In reality the car has no "throttle". It's a drive by wire and even that is a bit misleading. The car reads the throttle position as a "torque request" then calculates what boost and throttle butterfly opening (and all the rest) is needed to generate, and adjusts accordingly. <p>There is no 1:1 relationship between the pedal and the throttle.

Re: (Needsdecaf)

where is the throttle position sensor? Is it difficult to replace? Might be worth a try for me, considering otherwise I will have to tow to the shop. oy!<p><i>Modified by iamnotmad at 9:03 PM 7-9-2009</i><BR><BR>

Re: (iamnotmad)

TPS is part of the throttle unit and I don't believe its replaceable separately. Luckily you can replace the throttle on these and not need new software but still need VIDA to command calibration.

Re: Any guidance on the following codes thrown? (iamnotmad)

I probably joined a bit too late and hopefully you have your issues resolved but......... there seems to be a lot of codes thrown at the same time. Any prior history before this? Any recent work done or mods?<br>

Re: Any guidance on the following codes thrown? (Denis)

Update:<p><br>The car is acting very normal now. I drove it a tiny bit just in the alleys behind my house. <p>Any chance this was a flukey thing? And this issue could be gone at least for a while? It seems like something should still be wrong. I guess I'll find out when I take it out today.<p>Oh, Denis, only recent service was spring seat replacement.<br><BR><BR>

Re: Any guidance on the following codes thrown? (iamnotmad)

ok, so the CEL came back on yesterday, and it's back in limp mode. Unfortunately my local shop suggested I take it to the dealer after I told him what was happening. So I guess I need to prepare for inflated repair costs. <p>I guess the throttle body (if that is what the prob is) is not under any kind of warranty outside the 4yr?<br><BR><BR>

Re: Any guidance on the following codes thrown? (iamnotmad)

Ok, so dealer says, after lots of time tracing the problem, it is the Electronic throttle actuator, which I guess is synonymous with electronic throttle module and electronic throttle body. Bottom line, with all of their time spent researching the problem $970. He took an hour of research time off, and I have a 15% off coupon, so it'll be around $825. Ugh. U guess it could have been worse. <p><br>I guess that semi-recall a while ago was pre-2004 models right (was it only up to 2000?)<p>

Re: Any guidance on the following codes thrown? (IwantaS60R)

Yeah, I know it's cheaper to order elsewhere, but there was not much I could do, and they knew it (the car was not really drivable). I'm sure they tacked on extra bs "research" time. Especially since I had a 15% off coupon. Ultimately, I paid $825 after my 15%. Still about $125 over what it should be I guess.<p>Without any actual evidence of how much it should cost (from a dealer) there's nothing I can do. Even with that they can just claim "research" time. <p>They did do an oil change for $30, that's about $20-$25 less than normal.<p>
