Great job! I was too lazy to type it. My OCR software would not convert it correctly.

Default RE: List of diagnostic trouble codes (DTC)

Thank you 94_850T[sm=smiley20.gif]for the listingof codes and terms, and thanks to JPN for getting me started.

I'm sure that not only myself but others will find this of great assistance.

I'm currently going throughthe Brick's codes and will clear and see what comes back and go from there.

Here is what I have found:

A3 Codes

142 - Stop lamp switch faulty
141 - Pedal signal faulty - Shorted to ground

A6 Codes

241 -
EGR system flow too low in system
214 -
Engine speed (RPM) sensor signal missing sporadically
324 -
Camshaft Position sensor signal missing sporadically
314 -
Camshaft Position sensor signal missing or faulty
131 -
Engine speed (RPM) sensor signal missing

A7 Codes

132-
No RPM sensor signal
122 -
Temperature signal interval too long

B1 Codes


122 -
Outside temperature sensor open circuit or shorted to 12 volts
132 -
Driver side air duct temperature sensor open circuit or shorted to 12 volts
134 -
Passenger side air duct temperature sensor open circuit/shorted to 12 volts
411 -
Blower fan seized or drawing excessive current
413 -
No control voltage at driver’s side interior temperature sensor inlet fan
414 -
Driver side interior temperature sensor inlet fan seized
415 -
Passenger’s side interior temperature sensor inlet fan shorted to earth
416 -
No control voltage at passenger side interior temperature sensor inlet fan
417 -
Passenger side interior temperature sensor inlet fan seized
418 -
No control signal to blower fan power stage

B2 Codes

122-
Abnormal speed signal.

Whew [sm=smiley5.gif], that is one crazy list and I'm really hoping that B1 codes aren't going to cost me an arm and a leg to repair. All I need to do now it find locations for all of this and I should be in business with no more warning lights on the dash.[sm=wootwoot.gif]

Anyway, it's like3am., and I need to drop and will[sm=type.gif] tomorrow(later today)and update my findings. Maybe I can clear a few.

I just tried doing the reset (which by the way was very easy to follow)...THANK YOU! Everything happend according to your instructions, but the check engine light did not go out. Is there something I'm not doing? I had this light on since November and we thought it was a mouse nest in my air filter...nothing has been wrong with my car since.

Any advice would be wonderful!

Hey now Tmixdorf,

http://www.volvoclub.org.uk/reset.shtml

Check for code from A7, clear and then follow the reset procedure in the link and you should be fine.

My (lambda/check engine) light came on last year due to an exhaust gasket leak and I went through and cleared them last weekend and it is so nice to NOT see that light on .

Now I just need t replace a front left ABS wheel sensor and the ABS and Tracs light should be put to rest and then I will be really happy with a clear dash [sm=smiley20.gif].

Sorry for the late reply. Been really busy lately and I am doing some touch-up's. Post pics later.

[:@]I have a '99 Volvo S70 B5254S (gasolin 2.4L 20V Automatic) with Motronic 4.4, the check engine lit up, shop says it is a 0012 code but they don't know what it means, the car runs fine.

Is that a generic P code?

I don't know. I have been told (not by the mechanic) that it may be related to the Camshaft position or its sensor

It looks like a P code and yes it means camshaft timing out.
Have you had the timing belt done lately?

No I bought the car recently and the last belt change was about 70K Km ago (50K miles), the car runs good, I see no change since the light came on, about 900 RPM at idle. i think i'll just disconnect the battery to turn the light off (don't have a code reader) and see what happens
Thank u
Israel

Try that and see if all else fails have the timing checked.

Default engine trouble codes

I have 1991 240 that surges while idling. It also is unresponcive when the troutle is pressed. I replaced the mass air flow and still receive the same engine codes, 223-121-113. Any help would be greatly appreciated

My 96 850 glt, has three codes in memory. (1) misfire on cyl 4 (2)rich condition from one of the sensors (3) random misfires

Car runs great and the previous owner said he drove the car for 2 years with the CEL on with no issues.

1)How can I check codes without an official obd2 scanner? Is there a plug I can jump to make the light blink or anything, like obd1 vehicles?

2) How do I clear these codes?

For 96 and 97 850 owners who want to read and erase codes for ECU, Transmission, Cruise Control and ECC (Electronic Climate Control) you can build this very simple OBD2 DIY Code Reader from this Document.

If you have a Wiring Diagram, you can also access the ABS and SRS diagnostic wire at the connector.
