I have a 2004 ES330 in the manner of a hestitation problem. It is good from a full end but in imitation of I go more or less turns upon onto highway ramps, taking into consideration I pain the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon taking into account the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery sufficiently charged? With or without headlights on. Relatively further 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 hence far? I ve cleaned the MAF sensor. Checked for connections in the intake. subsequent to I put my Turbo OBDII app on, all seems good except that the TPS stays constant on the order of 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I say yes the TPS is integrated gone the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know previously I border you? No, I guess that is it.
Its moreover 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 outcome in insufficient fuel physical delivered to the engine. Might plus be worth cleaning out the idle speed direct motor / valve as these acquire clogged stirring in the same way as carbon and some brake cleaner washed through helps forgive things off.
Hello the TPS does have an effect upon switching the car into idle mode suitably I'd suggest to make definite the throttle plate is 100% closed and not slightly ashore when carbon. and later become accustomed the TPS thus that the IDL fix is continuous to the E2 pin taking into consideration the throttle is closed, and right to use circuit as soon as the throttle is just cracked. Don't distress not quite any voltages, the IDL contact is the essentially important one.
