I have a 2004 ES330 like a hestitation problem. It is fine from a full end but next I go on turns upon onto highway ramps, with I afflict the accellarator (sp?) it hesitates for 2 seconds since 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 begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery abundantly charged? With or without headlights on. Relatively other 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 for that reason far? I ve cleaned the MAF sensor. Checked for associates in the intake. when I put my Turbo OBDII app on, all seems good except that the TPS stays constant as regards 30%. This is a drive-by-wire model hence it has not throttle cable or normal TPS. I allow the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know past I be next to you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests upon the expose flow meter and said it was good. taking into consideration I unplug it and govern the motor, the car runs uncompromising and at 850ish. I can deserted guess that my other 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 rule in the every other of rpm though? I think it single-handedly adjusts it just about 1k..
Hello the TPS does have an effect on switching the car into idle mode appropriately I'd recommend to make sure the throttle plate is 100% closed and not slightly grounded afterward carbon. and next become accustomed the TPS as a result that the IDL fasten is continuous to the E2 attach in the manner of the throttle is closed, and gate circuit subsequent to the throttle is just cracked. Don't make miserable very nearly any voltages, the IDL admission is the in point of fact important one.
