I have a 2004 ES330 next a hestitation problem. It is good from a full stop but once I go roughly turns on onto highway ramps, taking into consideration I depress the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon when the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery thoroughly charged? With or without headlights on. Relatively supplementary battery. Mechanic s Assistant: What is the model of your 04 Lexus? ES330 Mechanic s Assistant: Are you fixing your vehicle yourself? What have you tried consequently far? I ve cleaned the MAF sensor. Checked for contacts in the intake. subsequently I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant going on for 30%. This is a drive-by-wire model as a result it has not throttle cable or usual TPS. I tolerate the TPS is integrated behind the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know in the past I be next to you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests on the let breathe flow meter and said it was good. taking into consideration I unplug it and run the motor, the car runs unfriendly and at 850ish. I can isolated guess that my supplementary 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 govern in the swap of rpm though? I think it deserted adjusts it roughly speaking 1k..
Hello the TPS does have an effect on switching the car into idle mode suitably I'd suggest to make distinct the throttle dish is 100% closed and not slightly stuck taking into account carbon. and then familiarize the TPS appropriately that the IDL pin is continuous to the E2 stick behind the throttle is closed, and read circuit bearing in mind the throttle is just cracked. Don't badly affect practically any voltages, the IDL admission is the in point of fact important one.
