I have a 2004 ES330 following a hestitation problem. It is fine from a full stop but taking into consideration I go with reference to turns on onto highway ramps, gone I depress 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 like the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights direction on? Is the battery sufficiently 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 for that reason far? I ve cleaned the MAF sensor. Checked for contacts in the intake. with I put my Turbo OBDII app on, everything seems good except that the TPS stays constant concerning 30%. This is a drive-by-wire model correspondingly it has not throttle cable or usual TPS. I undertake the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know past I attach you? No, I guess that is it.
Might then be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can reach a quick deviation locate if you unplug the meter and rule the engine without it. if the engine condition is the same after that chances are the meter or the link to it is faulty. Its then worth cleaning the MAF sensor wires, as they can acquire coated following dirt more than era which later offsets the reading. Use some way in cleaner or brake cleaner to spray onto the wires to separate the dirt on no account lie alongside the wires afterward whatever as they are entirely fragile
Hello the TPS does have an effect upon switching the car into idle mode appropriately I'd suggest to make sure the throttle dish is 100% closed and not slightly ashore following carbon. and later familiarize the TPS appropriately that the IDL pin is continuous to the E2 fix following the throttle is closed, and door circuit subsequent to the throttle is just cracked. Don't upset very nearly any voltages, the IDL right of entry is the truly important one.
