Code 22, 34 and 43=bad ground?

Corolla_Frenzy · 10-07-2008, 08:40 PM

Low signal reading for TPS and MAP and electronic spark control=failure.

This is what the code reader just now said.

The service engine soon light has been on since the replacement engine went in.

I looked for the spark control unit and I don't see one at all on the new engine and old engine.

Could this all be due to bad ground?

Anyone else experience this?

Corolla_Frenzy · 10-08-2008, 04:34 PM

It's a tough one.

bump for help.

Is it the '97? Ignition Control Module (ICM) should be next to the coil.

Have you checked the fuses?

Corolla_Frenzy · 10-09-2008, 04:11 AM

Its the brilliant spider injected 95 once again plaguing my eye sight with service engine soon lights nonsense.

Yogi · 10-09-2008, 12:46 PM

I could be wrong but I believe that the '95s had the ICM in the dizzy and the Electronic Spark Control (ESC) on the firewall.

Could be a bad ground or bad fuse.

Corolla_Frenzy · 10-09-2008, 11:35 PM

I'd really like to know about those codes. I saw the part on the computer at a parts store and I don't have that. Must be inside it, but it didn't show any other kind of spark control module.

Corolla_Frenzy · 10-10-2008, 01:11 PM

Someones gotta know. Does nobody know or is it nobody cares? Is the answer in front of me and I'm blind?

Yogi · 10-10-2008, 01:25 PM

I'm working on a reply. Hold on.

Yogi · 10-10-2008, 01:33 PM

I'm not sure about the location for the ICM but here is what it looks like.
Click here for the ICM:

And click here for the cam position sensor which is in the dizzy:

Corolla_Frenzy · 10-10-2008, 02:24 PM

I have a cam sensor? lol Theres no code for that.

So I'll take a peak inside the dizzy for that ICM.

What are the symptoms (usually) when this ICM goes out? The blazer runs fine. It had a surging idle problem, but that was dizzy timing. Other than that could it be only a trigger for the service engine soon light?? I wouldn't put it past GM for that hahahhah!!!

Cam sensor is # 41 – "Camshaft Sensor Circuit"

Symptoms for a bad ICM vary widely. Could be as little as a slight miss to a motor that won't even start. And they can work intermittently. A motor may start and run fine when cold but die and not restart when hot. Motor cools down and restarts OK again.....

Corolla_Frenzy · 10-10-2008, 03:57 PM

I mean cam sensor isn't related to my problem at all....at least the codes don't show it to be an issue.

Are the Astro van and blazer distributors the same or different?

The cam sensor, knock sensor and ICM are all interrelated. Sometimes a defect in one can show an error code for the other.

I don't know for sure but the Astro and Blazer dizzys are prolly the same.

Corolla_Frenzy · 10-11-2008, 03:23 AM

I was having problems with the knock sensor....hmm...

Well the only thing I can do now is replace the dizzy, but how will that affect the MAP/TPS problem?

It may or may not solve it. I would check for the 5 v. supply to the MAP and TPS first. Check your fuses. Clean your grounds real good. Do this before you start swapping parts.

Corolla_Frenzy · 10-11-2008, 02:18 PM

I'm having a tough time remembering about grounds on the back of the cyl heads.
I've tried my best to forget the times I hated and it works sometimes. I know there's brackets that hold the wires on, but are they grounds, too or are there grounds back there at all?

Yogi · 10-11-2008, 02:35 PM

I don't know about the '95 but mine has a strap back there. Check the end of the negative battery cable too.
