The P1FFB automobile fault code indicates a problem with the HybridEV Powertrain Control Module 2.

The most common symptom is the Engine Light ON or Service Engine Soon Warning Light. The cause of this issue could be a faulty HybridEV Powertrain Control Module 2, an open or shorted harness, or a poor electrical connection. The importance of repairing this issue lies in the fact that it affects the performance of the hybrid or electric powertrain.

The repair difficulty is moderate, and the repair time is estimated at 1.0 hour.

To fix the problem, 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 interpret the fault code correctly to identify the root cause of the problem.

The automobile fault code P1FFB has an estimated repair time of 1.0 hour. The cost of fixing this fault code varies between $75 and $150 per hour, depending on the auto repair shop. The cost of fixing this fault code is influenced by factors such as the severity of the problem, the type of vehicle, and the location of the repair shop.

Other factors that may affect the cost of fixing this fault code include the availability of replacement parts and the expertise of the mechanic.

The P1FFB code refers to the HybridEV Battery Pack Coolant Level Sensor Circuit.

The level sensor is attached to the coolant surge tank and uses a bi-metallic reed switch to change state when exposed to magnetism.

The powertrain control module 2 supplies 5V to the signal circuit and a ground for the low reference circuit.

The resistance of the sensor decreases when the battery coolant level gets low, allowing the powertrain control module 2 to determine if the system is low on coolant.

What are the possible causes of the P1FFB automobile fault code?

If you’re experiencing the P1FFB fault code, you may notice that your engine light is on. This code is typically caused by a faulty Hybrid/EV Powertrain Control Module 2, an open or shorted harness, or a poor electrical connection in the Hybrid/EV Powertrain Control Module 2 circuit. To fix the issue, it’s important to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
