The P2608 fault code in automobiles refers to a problem with the Intake Air Heater (IAH) system. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light.

The cause of this issue could be a faulty IAH relay, a faulty IAH, or poor electrical connections in the IAH circuit.

The repair importance is moderate, as it can affect the engine’s performance and fuel efficiency. The repair difficulty is low, and the fix involves visually inspecting the wiring harness and connectors for damage and checking for broken or corroded pins.

The repair time is estimated to be around 1.0 hour.

To interpret the fault code, one needs to check the possible causes listed above and visually inspect the related components.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level10.0 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2608 fault code. Here are the symptoms to look out for:

  • The P2608 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include issues with the engine’s performance, such as reduced power or acceleration, stalling, or rough idling.
  • The vehicle may also experience problems with its emissions system, such as increased emissions or failing an emissions test.
  • Additionally, the vehicle’s fuel efficiency may decrease, and there may be issues with the transmission or other systems.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code p2608 can be caused by a range of issues, including a faulty IAH relay and poor electrical connections.

  • The automobile fault code P2608 can be caused by a faulty Intake Air Heater (IAH) Relay, a faulty Intake Air Heater, an open or shorted Intake Air Heater Relay harness, a poor electrical connection in the Intake Air Heater Relay circuit, an open or shorted Intake Air Heater harness, and a poor electrical connection in the Intake Air Heater circuit.

Below are the possible fixes for the automobile fault code p2608, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2608, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2608 indicates a problem with the auxiliary coolant pump control circuit. The estimated repair time for this fault is 1.0 hour.

The cost of fixing this fault will depend on the hourly rate charged by the auto repair shop.

Most shops charge between $75 and $150 per hour.

Therefore, the cost of fixing this fault can range from $75 to $150.

The P2608 code refers to the Intake Air Heater ‘B’ Circuit High. The Engine Control Module (ECM) uses an Intake Air Heater (IAH) to warm the incoming air for proper cylinder combustion. The IAH relay is grounded by the ECM to energize the heater during cold operation.

The IAH is commanded ON when the engine coolant temperature is below 40 C (104 F). The IAH heater is supplied power by the battery positive voltage circuit through the IAH relay.

What are the possible causes of the P2608 automobile fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P2608 fault code. This code is caused by a faulty Intake Air Heater (IAH) Relay, faulty Intake Air Heater, open or shorted Intake Air Heater Relay harness, poor electrical connection in the Intake Air Heater Relay circuit, open or shorted Intake Air Heater harness, or poor electrical connection in the Intake Air Heater circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
