2003 Volvo V70 Engine Diagram

Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super spread around car that I am ready to drive off a cliff. had a idle surge suffering that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After irritating 2-3 every second used IAC s, I took it to the master tech at lexus. He said it was the IAC valve. He tried my used ones.. and finally a rebuilt one. yet had issues. support to the dealer.. this epoch he says, it needs a ECU. I did a lot of research upon them, and found that its a common burden in imitation of this car.. bought a used one.. more trouble. had the native one rebuilt by a specialist.. and that s where I am at now.. Put it in tonight and the car idles at 2k rpm. Does the TPS infatuation to be re-adjusted? The master tech did all sorts of diagnostics upon every combined parts (tps, maf, iac). $100-200 every epoch I take it complete the dealer for diagnostics.. upon going problems are really adjunct up. I m unsure to adjoin the tps if he had it dialed. Any insight? Thanks in advance. Jason

I did re-check them tho. The master tech did extensive tests on the ventilate flow meter and said it was good. taking into account I unplug it and govern the motor, the car runs severe and at 850ish. I can and no-one else guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much run in the vary of rpm though? I think it solitary adjusts it almost 1k..

Hello the TPS does have an effect upon switching the car into idle mode for that reason I'd recommend to create definite the throttle dish is 100% closed and not slightly grounded like carbon. and after that accustom yourself the TPS as a result that the IDL pin is continuous to the E2 fix following the throttle is closed, and retrieve circuit with the throttle is just cracked. Don't cause problems not quite any voltages, the IDL admittance is the in point of fact important one.
