I have a 2004 ES330 with a hestitation problem. It is fine from a full stop but in the manner of I go approaching turns on onto highway ramps, similar to I upset 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 in imitation of the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery fully charged? With or without headlights on. Relatively further 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 so far? I ve cleaned the MAF sensor. Checked for contacts in the intake. following I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant vis--vis 30%. This is a drive-by-wire model suitably it has not throttle cable or usual TPS. I take the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know previously I connect you? No, I guess that is it.
Might in addition to be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can realize a quick anomaly locate if you unplug the meter and rule the engine without it. if the engine condition is the thesame subsequently chances are the meter or the membership to it is faulty. Its moreover worth cleaning the MAF sensor wires, as they can acquire coated in the same way as dirt on top of mature which then offsets the reading. Use some get into cleaner or brake cleaner to spray onto the wires to separate the dirt upon no account adjoin the wires next everything as they are entirely fragile
Hello the TPS does have an effect on switching the car into idle mode appropriately I'd suggest to make definite the throttle dish is 100% closed and not slightly high and dry when carbon. and later accustom yourself the TPS hence that the IDL fasten is continuous to the E2 glue taking into consideration the throttle is closed, and retrieve circuit in the same way as the throttle is just cracked. Don't badly affect about any voltages, the IDL read is the really important one.
