The P1AF7 automobile fault code refers to a problem with the Power Inverter Control Module (PIM) in hybrid electric vehicles. The symptom is an illuminated Engine Light or Service Engine Soon Warning Light. The cause could be a faulty PIM, an open or shorted PIM harness, or poor electrical connection in the PIM circuit.
The repair importance is high as it affects the vehicle’s performance and fuel efficiency. The repair difficulty is moderate, with a repair time of 1.0.
To fix the issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
It is essential to check the possible causes listed above to interpret the fault code.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |
| Repair Difficulty Level | 10.0 (Out of 10) |

The fixing cost will depend on the severity of the issue and the parts that need to be replaced. The estimated repair time for this fault code is 1.0 hour, which means that the labor cost will be between $75 and $150.
It is important to get this issue fixed as soon as possible to avoid further damage to the hybrid battery system.
P1Af7: The Low Voltage Battery System – Diagnosis And Solutions
The P1AF7 code is related to the Drive Motor 2 Control Module Hybrid Battery Voltage Isolation Sensor Circuit. The Motor Control Modules (MCMs) measure the hybrid battery High Voltage (HV) with internal sensors. The MCMs test for Loss Ff Isolation (LOI) between the HV positive or negative circuit and vehicle chassis.
The MCMs detect LOI through two high-impedance resistors and voltage measuring circuitry.
The MCMs monitor the LOI voltage measuring circuitry for correct operation.
The code indicates that the sensor circuit is detecting high voltage, which may indicate a loss of isolation.
FAQ
If you see the engine light on or service engine soon warning light in your automobile, it could be due to the P1AF7 fault code. This fault code can be caused by a faulty power inverter control module (PIM), an open or shorted PIM harness, or a poor electrical connection in the PIM circuit. To fix this issue, you should reprogram the PIM and visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
