I have a 2004 ES330 in the manner of a hestitation problem. It is fine from a full end but in the manner of I go almost turns upon onto highway ramps, next I distress the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon subsequent to the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery abundantly 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 correspondingly far? I ve cleaned the MAF sensor. Checked for links in the intake. subsequent to I put my Turbo OBDII app on, anything seems good except that the TPS stays constant in this area 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I acknowledge the TPS is integrated once 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.
I did re-check them tho. The master tech did extensive tests upon the expose flow meter and said it was good. later than I unplug it and rule the motor, the car runs harsh and at 850ish. I can forlorn guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much direct in the substitute of rpm though? I think it lonely adjusts it as regards 1k..
Hello the TPS does have an effect upon switching the car into idle mode thus I'd recommend to make clear the throttle plate is 100% closed and not slightly grounded later than carbon. and next adapt the TPS suitably that the IDL fix is continuous to the E2 pin bearing in mind the throttle is closed, and approach circuit bearing in mind the throttle is just cracked. Don't upset very nearly any voltages, the IDL entre is the in fact important one.
