Engine check light with code p1589 - 2007 Toyota Yaris

Question edited for clarity and all the typos.

Usually, you remove and clean the electronic sensor that is attached to the accelerator pedal. After disconnection and cleaning, it will relearn. Clean the Throttle body at the same time which is at the other end of the process.

Hello - this diagnostic code, P1589, is a throttle relearning error - typically done after a throttle control unit is replaced. This error occurs during deceleration testing, when the vehicle is almost at a stop - but the acceleration sensor in the vehicle doesn't register that deceleration correctly.

It's random misfire

P1589
Use a scan tool or Techstream and calibrate deceleration sensor. While performing the calibration follow on screen instructions.You can do the calibration by clicking Engine and ECT> Utility> Reset Memory> After that click "deceleration 0 point calibration" while you do that make sure that your car IGN switch is "ON", hand brake pulled and your gear shift is on "P" or Neutral. At last perform the CVT Oil Calibration.
Some automatic transmission DTCs cause the MIL to come on. If the MIL is on and no DTCs are indicated in the EFI system, select the A/T system, and check for automatic transmission DTCs.
If the problem persists, check the Yaw rate sensor for its position or replace the Brake Actuator Skid control ECU (ABS actuator assembly).

P1589 means TCU unable to control desired throttle angle, SO, it will not work right only erase the DTC with scanner, you should repair the throttle angle or related component. any other questions, you can ask the 24 hrs live technical support http://www.diyobd2.fr/, they will like to help you, good luck

The P1589 means Autolamp Delay Increase Circuit Short To Battery. you can erase the fault code with your obd2 scanner first, after then, if the check engine light comes on again, you should take it to be fixed.

You need the dealer to check the throttle blade control motor which is part of the electrically controlled throttle body, it may be defective.
