Mechanic s Assistant: Will the headlights incline on? Is the battery sufficiently charged? With or without headlights on. Relatively extra 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 hence far? I ve cleaned the MAF sensor. Checked for connections in the intake. similar to I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant more or less 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I believe the TPS is integrated past the throttle controller/motor.
