OBD1 DTC's

[2.0dude]

I have a newer version of the Bentley that only has OBD2 codes...

But I need some help interpreting these codes:
4431
2113
2324
4343
2111

Anyone help? TIA

I found a good site that has codes here http://www.12v.org/maintenance/dtc.php

4431 Idle Air Control Valve [N71].
2113 Camshaft Position Sensor.
2324 Mass Air Flow Sensor.
4343 EVAP Canister Purge Regulator Valve [N80].

IAC and MAF were cleaned a few months ago, but will re-clean them as a start. I'm not sure about the Cam Position Sensor and the EVAP codes though.

Any ideas on now I can address these?

I'd venture a guess that those two codes are related to the MAF.

I know its a stupid thing to ask..but hey, its a stupid thing to do - did you install the MAF facing the correct way.

Does your car have a big camshaft
When did you last do timing

[2.0dude]

sorry for the lack of details...perhaps i should provide a bit more background:

in the cold weather, my car has been running like a champ. chip+intake+exhaust are the main mods. normal idle is ~900rpm. the weather has warmed up quite a bit recently and i have noticed that the idle is always at ~2000rpm. so while trying to diagnose this problem, i opened up the hood and started to unplug different sensors.

it has suddenly dawned on me that the MAF and IAC have all been yanked while the engine was running, and likely threw a code that was logged. so i guess that leaves the camshaft position sensor code that is not accounted for. however, i dunno how that could affect my high idle problem. will need to chk the gas cap to see if EVAP goes away.

anyway, i am gonna clear all the codes and see what gets thrown tomorrow.

timing was done 1.5 years ago (~20K miles). MAF is installed OK.

[Pagano]

Do you have an aftermarket cam? Sometimes if its big enough it'll throw the cam code.

outside of that...

pulling those two sensors could of triggered the other two codes...clear everything and see what pops up in the next 24 hours

[2.0dude]

no aftermarket cam.

gonna clear the codes now and see wassup. stay tuned.

[2.0dude]

Just a short update.

I removed the IAC and cleaned it with throttle body cleaner. Then I reset the codes. Drove around and observed normal operation and idle. Rescanned and it threw a:
4431 Idle Air Control Valve [N71].

Still not convinced, I reset the codes once more. Idle was fine yesterday, but then today the high idle problem came back. I just scanned and the system threw a new code at me:
2212 Throttle Position Sensor.

Will keep u posted. Am thinking of resetting computer again and see the best 2 out of 3.

you using a jumper in the OBD connector, or a VAGCOM?
If a jumper, how are you resetting (clearing) the codes..?I need to do this, too.

[2.0dude]

see here:

"To Erase DTC memory
1. With the ignition key off, connect the jumper wire or the adapter to the diagnostic connector(s)

2. Turn the key on , wait at least 5 seconds and then disconnect the wire or adapter.

3. Reconnect the jumper wire or the adapter for 2.5 seconds and then remove it. The first DTC code (if present) will be displayed.

4. Repeat step 3 until mo more codes are displayed (DTC 4-4-4-4 displayed)

5. Reconnect the jumper wire or adapter for 2.5seconds and remove it. The DTC memory is now erased. Turn the ignition off.

To confirm that the memory has been erased repeat step 3. There should be only a 4-4-4-4 code (continuous long blinks) present."

awesome, 2.0dude! thanks!

Ok, heres MY update:
I followed the directions to pull all the codes from my ABA swap Cabby.. Heres what I got.. The desctiption of the error is from 12v.org.. (thanks for the heads up)

2111: Engine Speed Sensor (ESS)
2113: Camshaft Position Sensor (CPS)
2142: Knock Sensor 1 (KS1)
2342: Heated Oxygen Sensor
4343: EVAP Canister Purge Valve
And two not on the list of codes:
3434: ?
4312: ?

The car starts, runs, drives.. Gets mid thirties mpg..

I followed the steps to clear the DTCs, and after doing so, I only got back 2111, 4312 and 4343..
Anyone have any ideas as to what the trwo mystery codes are?

[2.0dude]

i got those mystery codes as well
3434 - Heated O2 Sensor Relay -> applies to VR engine
4312 - EGR Vacuum Regulator Solenoid

so u'r saying that u reset the codes and still managed to pull of those?

i would guess that it's probably a domino effect ...

[qwikxr]

Yep.. I was clearing codes. I never saw 4-4-4-4, but I got to where all it would do was 1 long flash, repeatedly.... THe same thing when I was pulling codes.. once it seemed to be the last code stored, then next time I jumpered it, got the long flashes repeating.. like it was done or something.

wonder why I get the mystery vr6 codes?

edit: Oh, yeah, once I got the long flashes after clearing, I cycled the ignition, started the car, the CEL came on immediately.. Checked it, and pulled those codes listed...
I do know, that my O2 heater relay isnt working.. I need to trace signals and find out why...
The EVAP solenoid is throwing codes, because it isnt in the car.. I might plug it in and see if the code disappears..
The EGR is removed, too..
CPS and ESS codes... no flipping clue..

ESS code is normal if u r pulling the codes when the motor is not running (as per Bentley, but also makes sense cuz there is no engine speed)

[qwikxr]

HA! didnt even think of that! No friggin wonder I got CPS and ESS codes
Im such a dumbass sometimes! lol

[entrojetta]

I believe my bentley says it will display 1-1-1-1 when all the codes are cleared, not 4-4-4-4. am i crazy or are you crazy?

[qwikxr]

well, Im going with 1-1-1-1

[digitalhippie]

how bout these:

4411
4412
4413
4414
1321
1322

Also had: (but these are already defined above)
2111
3434
4312

[qwikxr]

ok, i ran codes again:
KOEO:
4412
4413
4414
1321
1322
3434
4312

Installed Purge solenoid, connected EGR solenoid. Cleared the codes, started the car, CEL on.. while running ran codes..

KOER:
4312
2111
1-1-1-1

So I turned it off, then went through the CLEAR CODE steps: and saw these while clearing..

KOEO-Clr:
1322
4312
3434
1321
1322
4411
4412
4413
4414

Last 4 are injectors..
I can't friggin win! lol

[digitalhippie]

qwikxr - I'm getting the EXACT same codes on my 93...

[qwikxr]

Well, I ordered VAGCOM yesterday.. So I guess I'll wait for it to show.. See if I can get this crap straight..
I hate cars..

[2.0dude]

UPDATE:

I replaced the throttle body/TPS. Cleared the codes. Will continue to monitor.

BTW, I had to reset the ECU (unplugged battery for a few min) in order for my idle to recalibrate. I guess the computer was still managing air/fuel/ignition based on my old throttle body, causing my car to idle at 2300rpm.

Also replaced my O2 sensor and fuel filter.
