The automobile fault code P1A8E has an estimated repair time of 1.0 hour.

The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the fixing cost of P1A8E will depend on the hourly rate charged by the repair shop.

It is important to consider these factors when budgeting for the repair of this fault code.

The P1A8E fault code indicates a problem with the 14 Volt Power Module Voltage Sensor Circuit.

The StarterGenerator Control Module (SGCM) monitors the voltage sensor to detect any failure of the APM 12-volt voltage sensor circuit below or above the valid range.

The APM 12-volt output voltage is used for a 12-volt line APM output voltage control and a 12-volt line voltage sensor rationality check.

What are the possible causes of the P1A8E automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1A8E fault code. This code is caused by a faulty 14 Volt Power Module Voltage Sensor, an open or shorted harness, or a poor electrical connection in the sensor circuit. 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.
