Your need something with a full Group 87 in it, TP3942202 S80 1999 Late Version Wiring Diagrams.pdf should be the same for the CCM.

Found this in VIDA. Vehicle profile set to 1996 AME 850. Information type: Specifications, mechanical. Search all for "Rear wheel hub" you should find it. One thing Volvo is infamous for is: midyear production changes that are not uniform across the production plants. Jim Bee: What is the ...

Volvo Diagnostic trouble code (DTC) format: Control Module-DTC number. The three character alpha prefix is the control module, in this case ECM (Engine Control Module). The suffix is the Diagnostic trouble code (DTC). A conversion table not worth much for this code because Volvo ECM-6806 = P1237. P1...

Have you considered converting it to automatic Overdrive with a Solenoid Bypass Kit and be done with the the original design issues?

All four of the codes are Long-term fuel trim. Yes a air leak can cause all of them. Any air leak after the MAF sensor can be the cause. If the air leak is on the intake side, you can locate it with starting fluid. With the engine cold, start the engine. Spray starting fluid around the intake, hoses...

The control modules have some AI code in them. Sometimes you need to force the AI to rethink. Try disconnecting the camshaft position sensor, give it an extended crank, see if it will fire up on the lookup tables. If it does, let it run for a couple of minutes. Shut down engine, camshaft position se...

Henry, User name doublebug, can do it over the internet but, you do need a DiCE unit on your end.

P0190 - ECM-280B: Fuel pressure sensor. P0188 - (ASE): Fuel Temperature (Sensor B) Circuit High ... I don't think Volvo ever used P0188. For the PCV, do the glove test. Tie down the glove so that it does not get sucked into the engine if it passes. Fail: If the glove stands up. Pass: If the glove su...

Figured there was something wrong with the information. I could not find a fuel pressure sensor or a fuel temperature sensor. Replacing a oxygen sensor (HO2S) should be the last resort. Keep looking for leaks in both the intake and exhaust systems. ---------------------------------------------------...

I hear you on the overhead support. My seller has a 98% Positive feedback but if you look through the negatives. Most of it is people that cannot figure out how to extract 6+ GB of compressed data off a 4GB DVD. To anybody reading this: If you are willing to wait for the shipment to come from Shenzh...
