    Hello. I have a 2007 Toyota Highlander sport – AWD, around 250k miles. I had my Highlander sitting a while because it needs bushings that have been hard to find. I was starting it occasionally & did have to jump it a couple of times (old battery, but now replaced). I started it the one day and the idle was really low. Check engine light & VSC were on. Got the idle up and tried to move it, but no response from accelerator. No reversed polarity & all fuses are good. It’s showing 2 codes – P2118 & P2138. Everything I have read has been from reverse polarity & a blown ECTS fuse, but not the case with mine. Not sure what else to try. It was working fine a few days before this.

    You need to do a bit more research
    When is the code detected? The Engine Control Module (ECM) monitors the battery supply voltage applied to the electronic throttle actuator. When the power supply voltage drops below the threshold, the ECM concludes that the power supply circuit has an open circuit. A DTC is set and the MIL is turned on.
    Considering you state you had a low / dead battery and needed to jump it the following falls in place.
    Possible causes for P2118 2007 Toyota
    Faulty Throttle Actuator Control Actuator
    Electronic Throttle Control System (ETCS) harness is open or shorted
    Electronic Throttle Control System (ETCS) circuit poor electrical connection
    ETCS fuse ECM

    P2138 TOYOTA Possible Causes What does this mean?
    Faulty Accelerator Pedal Position (APP) Sensor
    Accelerator Pedal Position (APP)
    Sensor harness is open or shorted
    Accelerator Pedal Position (APP) Sensor circuit poor electrical connection
    Faulty Engine Control Module (ECM)
