I have a 2004 ES330 afterward a hestitation problem. It is good from a full stop but past I go in relation to turns upon onto highway ramps, considering I afflict the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon afterward the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights turn on? Is the battery fully charged? With or without headlights on. Relatively new 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 therefore far? I ve cleaned the MAF sensor. Checked for contacts in the intake. behind I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant in relation to 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I put up with the TPS is integrated following the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know past I affix you? No, I guess that is it.
Might also be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can realize a quick irregularity find if you unplug the meter and run the engine without it. if the engine condition is the similar then chances are the meter or the connection to it is faulty. Its next worth cleaning the MAF sensor wires, as they can acquire coated once dirt more than become old which next offsets the reading. Use some entry cleaner or brake cleaner to spray onto the wires to cut off the dirt on no account be next to the wires considering anything as they are no question fragile
Hello the TPS does have an effect on switching the car into idle mode consequently I'd recommend to make determined the throttle dish is 100% closed and not slightly ashore behind carbon. and subsequently accustom yourself the TPS thus that the IDL glue is continuous to the E2 glue afterward the throttle is closed, and retrieve circuit later than the throttle is just cracked. Don't cause problems very nearly any voltages, the IDL get into is the really important one.
