I have a 2004 ES330 later a hestitation problem. It is fine from a full end but subsequently I go on the subject of turns upon onto highway ramps, with I sadden the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in imitation of the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery sufficiently 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 connections in the intake. subsequently I put my Turbo OBDII app on, all seems good except that the TPS stays constant in this area 30%. This is a drive-by-wire model thus it has not throttle cable or usual TPS. I consent the TPS is integrated gone the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know in the past I connect you? No, I guess that is it.
Its also worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a under the weather pump will every repercussion in insufficient fuel living thing delivered to the engine. Might in addition to be worth cleaning out the idle promptness control motor / valve as these get clogged in the works when carbon and some brake cleaner washed through helps release things off.
Hello the TPS does have an effect on switching the car into idle mode correspondingly I'd recommend to create sure the throttle dish is 100% closed and not slightly stranded afterward carbon. and after that adapt the TPS for that reason that the IDL attach is continuous to the E2 fix taking into account the throttle is closed, and admission circuit subsequently the throttle is just cracked. Don't distress not quite any voltages, the IDL contact is the in reality important one.
