I have a 2004 ES330 next a hestitation problem. It is good from a full end but later I go regarding turns upon onto highway ramps, bearing in mind I depress the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon afterward the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery fully 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 consequently far? I ve cleaned the MAF sensor. Checked for contacts in the intake. in imitation of I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant as regards 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I give a positive response the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know past I connect you? No, I guess that is it.
Its in addition to worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a below par pump will every outcome in insufficient fuel inborn delivered to the engine. Might afterward be worth cleaning out the idle enthusiasm rule motor / valve as these acquire clogged up past carbon and some brake cleaner washed through helps release things off.
Hello the TPS does have an effect upon switching the car into idle mode hence I'd recommend to create positive the throttle plate is 100% closed and not slightly stuck in the same way as carbon. and subsequently adjust the TPS fittingly that the IDL pin is continuous to the E2 pin afterward the throttle is closed, and admittance circuit later than the throttle is just cracked. Don't make miserable virtually any voltages, the IDL entrance is the essentially important one.
