The automobile fault code P1B03 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of diagnosis and fixing of the P1B03 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time.

The P1B03 fault code is related to the drive motor position sensor. The motor control module monitors the position, speed, and direction of the drive motor rotor. The position sensor contains a drive coil, two driven coils, and an irregular-shaped metallic rotor.

The DTC is set when the motor control module is unable to track the motor position based upon the sensor signals. The drive motor 1 position sensor is serviceable separately from the drive motor assembly.

What are the possible causes of the P1B03 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1B03 fault code. This code is caused by a faulty drive motor 1 position sensor, an open or shorted harness, poor electrical connection in the sensor circuit, or a faulty power inverter module. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
