I have a 2004 ES330 behind a hestitation problem. It is fine from a full stop but like I go in this area turns on onto highway ramps, subsequently I upset the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon like the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint 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 for that reason far? I ve cleaned the MAF sensor. Checked for connections in the intake. in the manner of 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 in view of that it has not throttle cable or normal TPS. I assume the TPS is integrated gone the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know since I affix 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 attain a fast malfunction find if you unplug the meter and manage the engine without it. if the engine condition is the similar next chances are the meter or the association to it is faulty. Its then worth cleaning the MAF sensor wires, as they can get coated in imitation of dirt higher than era which later offsets the reading. Use some approach cleaner or brake cleaner to spray can onto the wires to surgically remove the dirt upon no account be adjacent to the wires gone everything as they are extremely fragile
Hello the TPS does have an effect upon switching the car into idle mode as a result I'd recommend to create determined the throttle dish is 100% closed and not slightly grounded in imitation of carbon. and next become accustomed the TPS fittingly that the IDL pin is continuous to the E2 glue when the throttle is closed, and get into circuit similar to the throttle is just cracked. Don't worry roughly any voltages, the IDL entrance is the in point of fact important one.
