I have a 2004 ES330 subsequent to a hestitation problem. It is fine from a full end but following I go around turns upon onto highway ramps, past I sadden 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 consideration the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant 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 correspondingly far? I ve cleaned the MAF sensor. Checked for associates in the intake. subsequent to I put my Turbo OBDII app on, anything seems good except that the TPS stays constant all but 30%. This is a drive-by-wire model suitably it has not throttle cable or normal TPS. I take the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know past I link up you? No, I guess that is it.
Its along with worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a not at your best pump will every outcome in insufficient fuel innate delivered to the engine. Might in addition to be worth cleaning out the idle readiness rule motor / valve as these acquire clogged occurring later carbon and some brake cleaner washed through helps clear things off.
Hello the TPS does have an effect on switching the car into idle mode hence I'd recommend to create definite the throttle dish is 100% closed and not slightly stuck considering carbon. and subsequently familiarize the TPS appropriately that the IDL pin is continuous to the E2 pin subsequently the throttle is closed, and read circuit similar to the throttle is just cracked. Don't bother just about any voltages, the IDL read is the essentially important one.
