    TPS and ICM Question

    Yeah, I think they are. When I check codes it says IP2510 - IP2511 - IP2515. But the steering wheel controls are messed up so they gotta be B.. Never can figure all these codes out. Like the RS0061 - IR2255.

    I do remember there was a P0101 code, but it's not there anymore at all. Also, if I unplug it the car stays the same. I thought they usually stall out when unplugged. But again, there isn't a current or history code for that anymore.

    Just re checked.. Current codes are: P1634 - P2511 - C0073 History are: P1599 - P1644 - P1552 - P2510 - P2515 - P1558 - RS0061 - IR2255 -

    OK, Thanks! The guy mentioned that there was also an electrical problem. That's the P1634. I don't remember the numbers, but he said something like the current was low and he said it should be at a certain number, but it wasn't. I just don't remember what the numbers were.

    Nope! Don't have those. The shop did a video of the smoke test and there was a lot of smoke coming out at both ends. Also, the MAF if bad. Gotta replace that too.

    Thanks! I watched a few videos on removal and I would need to buy the fuel line tool. I get intimidated very easy. I thought I was gonna have a heart attack doing the throttle body removal. This is way worse. LOL.. The problem is now constant. The next choice, if it's cracked, do I get a new one, or try one from the junkyard? There are plenty of these cars in the junkyard. HA! Now that I mention the junkyard, I may just go there and take one off there first just for practice. It'll cost $3.00 to get in, but that's it if I screw up. LOL..

    I'm not really able to get my fingers in where the blowby is, but, I took the car to another shop and they did a smoke test for a vacuum leak and it had smoke coming out on both sides of the intake manifold. They said it's possible that the intake is cracked, but won't really know for sure till they get in there and check. Problem is they're talking $300.00 just for the labor to R&R it. Could it be intake gaskets? I've been looking at videos on line for R&R the intake.. I'm kinda scared to try it myself.

I know I got a bit of an attitude and said I quit, but I'm not a mechanic and this is really nerve wracking for me. Anyways, hoping you'll excuse my attitude and chime in on this. Thanks!

    Current codes are P1634 - P2511 - P2515 - C0073 No, don't have access to scantool. No, don't hear anything coming from the engine. I'll look into the blowby valve in the afternoon. This was happening before I cleaned the TB. But I was very careful with the gasket after you said you did that. I'm positive the gasket is on correctly. I took the car to a mechanic and they couldn't find the problem. No vacuum leaks were found. They had the car for 4 days and their guess is a bad PCM. I don't really want to sink a lot of money into this car, but I need it for a few more months. It's a hard fix because it's my car. Anyone else and it would be a vacuum hose standing there waving at you like one of these inflatable dudes. LOL.. Just the luck I have.. HA!

    Are you talking about the Idle Control Valve? I replaced that and the The Throttle Position Sensor.

    TPS and ICM Question

    Well dealer wants $250.00 to check it so it's not going there. So, can anyone answer this question? Going back to the P1634 Code in this post. If the splice in the harness was bad, would that cause the idle problem, or is that just a totally different issue all together???? It gets extremely high. 4000+ RPM's Took the wife to Tampa airport and was doing 75MPH over the bridge without touching the gas. It's getting to the point where I can't drive it anymore. My rotors are warped from riding the brakes and they're getting so hot they're failing. Just too dangerous to drive anymore.

    OK folks, in case anyone was wondering. Took the car to a mechanic and they couldn't find the extremely high idle problem. No vacuum leaks were found. They had the car for 4 days and their guess is a bad PCM. They didn't charge me so the next step may be the Caddy dealer. Going back to the P1634 Code. If the splice in the harness was bad, would that cause the idle problem, or is that just a totally different issue? There are soooo many posts about this high idle problem and every one of them has no fix and no posts to let anyone know if it was ever fixed and what the problem was. I will update if it ever gets fixed.

    Thanks again for the info, but I quit. I'm not going any further into the harness. Would have been a lot easier if I did this when the TB was off. It's just too darn hot out to keep messing with this and I have no idea what the heck I'm doing. Don't even know 100% if this is the problem. I'm not gonna need this car too much longer so I'll deal with it and then send it to the yard. Actually, I'll try and sell it for $4 or $500 first. Junkyards only gonna give me around $290.00.. Maybe someone will buy it for the wheels and Vogues.. 👍

    I looked at ever inch that can be seen and there is no part of the wire harness that I can see that's been chewed on. I'm not a mechanic and have no idea how to read schematics. As I've said many time here on this site I have no clue as to what I'm doing, so I need a little more info than most of you guys. But, it doesn't matter anymore. I'm done. I give up.. I'm just gonna drive it till it blows and then the junkyard can have it. So anyways, thanks again for the info.

    OK, any idea how far up into the harness it'll be? I untaped another inch or so after this pic. Would you know what color the wires are? I'll look through it again tomorrow. Thanks, Logan! 😀 👍

    TPS and ICM Question

    Well I don't really know what it is I'm looking for, but the wires look fine. No chew marks at all in the harness. Everything was in nice and tight and the plugs are clean as is the pcm. I don't see any kind of splice so I don't know what else to look for. 😣 😠 😢
