I have a 2004 ES330 later a hestitation problem. It is good from a full stop but subsequently I go all but 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 later the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery abundantly charged? With or without headlights on. Relatively additional 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. following I put my Turbo OBDII app on, anything seems good except that the TPS stays constant around 30%. This is a drive-by-wire model consequently it has not throttle cable or usual TPS. I acknowledge the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know previously I link up you? No, I guess that is it.
Might after that be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can reach a quick irregularity find if you unplug the meter and direct the engine without it. if the engine condition is the similar later chances are the meter or the membership to it is faulty. Its next worth cleaning the MAF sensor wires, as they can get coated once dirt beyond become old which after that offsets the reading. Use some read cleaner or brake cleaner to spray onto the wires to cut off the dirt on no account adjoin the wires afterward all as they are certainly fragile
Hello the TPS does have an effect upon switching the car into idle mode for that reason I'd suggest to make clear the throttle dish is 100% closed and not slightly beached taking into consideration carbon. and then adjust the TPS therefore that the IDL stick is continuous to the E2 glue in imitation of the throttle is closed, and approach circuit later than the throttle is just cracked. Don't trouble not quite any voltages, the IDL way in is the in point of fact important one.
