Order Of Error Codes

This is kinda strange. I am beginning to think it is a "Ghost In The
Machine" issue.

Anyways, I have posted about my error codes. If I recall correctly, the
sequence of error codes was:

12 15 46 25 24 23


Now, 12 I know is a no biggie code. 46 came up only a couple times and I
have not seen it in a couple days. So, last night, right before I replaced
the TPS unit, I did a code check and got this:


12 15 25 24

In that order.


After replacing the TPS, I drove the car around the block for testing and
when I got back, I did the error code check again.


This time the order was

12 24 15 25


As you can see, the TPS error code is still there but has shifted position
from the last on the list to the second. Now, I am thinking that there may
be an adjustment period before the error code will clear.

But is the order that the error codes appear in significant?

 

If these codes were read correctly, the vehicle doesn't run or drive very
well right now.

12, Start of codes
15, Vehicle speed/distance sensor signal absent
46, Charging system fault
25, Target idle speed not attainable (usually AIS-related)
24, Throttle position sensor voltage out of range
23, Air temp sensor fault

You didn't mention the 55 (end of codes), did you get it? You'll ALWAYS
get a 55 at the end of the flash codes, so if you didn't, then you counted
flashes wrong.

Test your charging system and examine the wire connections carefully,
especially at the alternator -- trouble's brewin'.

OK, are you clearing the codes each time?

That sounds as though you're *not* clearing the codes each time.
Disconnect either the negative battery cable or the pull-apart main
disconnect in the positive battery line about 6 inches from the battery,
and leave it disconnected for 2 minutes or so, then reconnect it, drive
the car and recheck your codes.

No.

The 46 code have something to do with each fault, , if the voltage is out of
range it could cause faulty readings on the sensors. the first step in
trouble shoooting these faults is to make sure the proper voltage is correct

 

Actually, at the time it ran TOO well.. See 4500 RPM thread..

Yes, I did get the 55 Error code, but simply failed to mention it, as I
understood what it meant.

This car has been flooded, thanx to our wonderful hurricane season we
just finished up down here in Central FL. I suspect some of the
electrical connections are a tad wanky, hence the inconsistency in the
error codes.

I did not clear the codes as I wasn't aware this was necessary. Thanx
for the heads up. I will do that tonight.

Thanx again.

So now is a good time to probably either:

1) Pull all of the electrical connections that one can get at apart,
clean the contact and apply dielectric grease.

2) Sell the car.

 

Option one is my best bet as option two has already been vetoed by the
spousal unit. Regardless of it's problems or the hassles, she loves her
car.

While I have ya'all reading, does anyone know what vicinity of the car the
VSS (Vehicle Speed Senor) that is attached to the transaxle is located?

Thanx

Well, looks like I have had quite a bit of success. I DID find the VSS
and replaced it. Put the TPS back on like I had it.

Cleared the error codes as previously directed and VIOLA.....

Error codes show 12 then 55. A very good thing.

I have yet to test drive very far so I am not sure if it is still
stuttering like it was last night. But the BAD news is, the Speedometer
still does not work.

I am guessing it is the Pinion Factor on the PCM that is unset. However,
I was told this could only be set by a dealer.

It'll always show 12 and 55 after clearing but before test driving.

Please let me know what this turns out to be.
I have a 90 dodge spirit that had fault codes 15 and 24. I have to pump the
gas to keep it running. I disconnected the battery to clear out the fault
codes, started the car and kept it running for a few minutes. Checked the
error codes - nothing. Started the car again and kept it running until it
warmed up. Checked the error codes - nothing. Started the car again and
took it for a few laps around the park & ride (where it conveniently broke
down - 40 minutes from home). Checked the error codes again - still
nothing. I was originally told it was probably the AIS, so I blindly
replaced that (before checking the fault codes). After I checked the fault
codes the first time, I bought a new TPS and installed it - nothing. I
ended up putting the old one back in and putting the new one back in the box
and put it on my shelf 'just in case'. Right now, it's looking like it's a
fuel pump issue (or ASD relay).

Looks like my happiness was premature....

I did the error code test and then did a test drive.

Before the test drive, all I got was 12 and 55.

After the test drive, the VSS code (15) popped back up.

I cleared the codes.

12-55 again.

Did a test drive.

12-15-55.

Arrrggghhhhhhh

Have you inspected the VSS socket carefully to make sure the terminals
haven't spread? Squeeze them with a pair of pliers through the rubber boot
if necessary; make sure they're making good contact.
