Rav4 Ac Wiring Diagram

Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super broadcast car that I am ready to drive off a cliff. had a idle surge pain that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After trying 2-3 oscillate 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. nevertheless had issues. put up to to the dealer.. this period he says, it needs a ECU. I did a lot of research on them, and found that its a common trouble with this car.. bought a used one.. more trouble. had the indigenous 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 compulsion to be re-adjusted? The master tech did all sorts of diagnostics on every aligned parts (tps, maf, iac). $100-200 every mature I assume it complete the dealer for diagnostics.. on going problems are in point of fact calculation up. I m of two minds to lie alongside 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 upon the expose flow meter and said it was good. taking into account I unplug it and direct the motor, the car runs uncompromising and at 850ish. I can abandoned guess that my additional rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much direct in the alternating of rpm though? I think it isolated adjusts it concerning 1k..

Hello the TPS does have an effect on switching the car into idle mode for that reason I'd recommend to make certain the throttle dish is 100% closed and not slightly beached considering carbon. and next become accustomed the TPS hence that the IDL pin is continuous to the E2 attach taking into account the throttle is closed, and read circuit taking into account the throttle is just cracked. Don't cause problems just about any voltages, the IDL read is the essentially important one.
