I have a 2006 GT with 209K miles. The throttle body has a cable running to it. I am looking to buy another vibe, and have found one, but there have been many delays, and now the issues that I have with my vibe are urgent - especially the exhaust in the cabin.
Thanks for reading. I appreciate the wealth of knowledge here. - Janet
I've posted before, and old problems have pointed to either a faulty IAC or ECU. New information came a couple days ago when my check engine light went on. Plus now my car is trying to poison me with CO.
Current Symptoms:
1. Check engine light on (P0505 and C1241)
2. Idle at 2K for the first 15 minutes of driving.
3. Heat not working well for the floor heat (an old problem, but maybe it relates to the next symptom.)
4. Exhaust getting into cabin from when I turn on the heat. This is my most major issue, even though the old debate of IAC or ECM seems to have just gotten some new clues. And I love to solve a good mystery.
I'll put my codes and what I did for them in chronological order:
3 -4 Years ago P2445 code triggered
Symptoms: After a clutch repair, the car would stall when taking my foot off the gas.
Work: I didn't replace anything
Results: Code went away, but stalling continued intermittently for the next few years, only in cold months when I was slowing or coming to a stop.
- Air pump fuse
- Vacuum hose
- Air pump assembly
- Faulty Pressure Sensor
- Air pump harness is open or shorted
- Air pump circuit poor electrical connection
- Pressure Sensor harness is open or shorted
- Pressure Sensor circuit poor electrical connection
A couple months ago: P0122 code triggered
Symptoms: car didn't start once after sitting in the cold for a day without pressing on the gas while turning key. And very high idle (up to 3k).
Work: I replaced the TPS, cleaned the throttle body, and replaced battery terminals and cleaned battery ground to frame.
Result: Idle is still high (2K) for the first 15 minutes of driving but not as high as 3K anymore.
- TPS not mounted securely
- TPS circuit short to ground or another wire
- Faulty TPS
- Damaged computer (PCM)
Most recent: P0505 code (triggered 4 times in 24 hours)
- Open or short in ISC valve circuit S PCV hose
- ISC valve is stick or closed*2
- A/C switch circuit
- Air induction system*2 S ECM
Most recent: C1241 (triggered once in 24 hours)- which auto zone said was the code for the ECU, but online says:
- Low Battery Charge
- Faulty Battery
- Faulty Charging System
- Power source circuit
Once I fix my garage door opener, I'll get my car in the garage and double check the battery connections. But since I just worked on them, I am pretty confident that they are okay... I hope...
Questions:
1. the code C1241 - is that for the ECU/ECM (they are the same thing right? close to the same as a PCM - the main computer for the car) or did auto zone's scanner tell me the wrong thing?
2. What does it mean that the P0505 code got thrown 4 times, and the C1241 only got thrown once. If the C1241 code is for the ECM, then that controls the IAC, so should I go after the ECM first? Or because the IAC code got thrown more times, go for that???
3. Is the exhaust that is getting into my car related to any of this, or is it a completely separate matter? This is the most concerning to me, because I would like to not pass out and die while driving to work. How would you go about solving it? I assume there has to be a leak somewhere - I can check the exhaust manifold to the catalytic converter to the muffler. My car recently passed emissions, but I have never replaced the muffler or catalytic converter on it. I can check for damage there, but should I also try to fix the floor heat? I assume that that would be a vacuum leak somewhere...
