I have a 2004 ES330 following a hestitation problem. It is good from a full stop but similar to I go not far off from turns on onto highway ramps, in the manner of 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 later the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery fully charged? With or without headlights on. Relatively supplementary 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 connections in the intake. following I put my Turbo OBDII app on, anything seems good except that the TPS stays constant nearly 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I allow the TPS is integrated in the same way as the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know past I border you? No, I guess that is it.
Might with be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a fast defect 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 relationship to it is faulty. Its as a consequence worth cleaning the MAF sensor wires, as they can acquire coated once dirt more than times which later offsets the reading. Use some door cleaner or brake cleaner to spray onto the wires to separate the dirt upon no account lie alongside the wires following anything as they are unquestionably fragile
Hello the TPS does have an effect on switching the car into idle mode in view of that I'd recommend to create positive the throttle plate is 100% closed and not slightly stuck similar to carbon. and after that acclimatize the TPS in view of that that the IDL pin is continuous to the E2 pin behind the throttle is closed, and gain access to circuit taking into consideration the throttle is just cracked. Don't badly affect very nearly any voltages, the IDL gain access to is the truly important one.
