The P2606 fault code in automobiles indicates 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 possible causes include a faulty IAH relay, a faulty IAH, or poor electrical connections in the IAH circuit or relay harness. The repair importance is moderate, as the IAH system helps to improve engine performance in cold weather. The repair difficulty is low, and the fix involves visually inspecting the wiring harness and connectors for damage or corrosion.

The fault code can be interpreted using an OBD-II scanner.

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 p2606 fault code.

Here are the symptoms to look out for:

  • The P2606 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 a decrease in engine power, poor acceleration, and reduced fuel efficiency.
  • Additionally, the vehicle may experience engine stalling or misfiring, and the transmission may shift roughly or erratically.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P2606 fault code in automobiles can be caused by a range of issues, including faulty relays and poor electrical connections.

  • The automobile fault code P2606 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.

To fix the p2606 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code P2606, 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 automobile fault code P2606 indicates a problem with the engine coolant pump control circuit. The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P2606 code refers to the Intake Air Heater ‘B’ Circuit RangePerformance. The Engine Control Module (ECM) uses the 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 powered by the battery positive voltage circuit through the IAH relay.

What are the possible causes of the P2606 automobile fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2606 fault code. This code is usually caused by a faulty Intake Air Heater (IAH) Relay, faulty Intake Air Heater, or poor electrical connection in the Intake Air Heater Relay 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.
