  • The P2607 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.
  • The vehicle may also experience rough idling or stalling, and the transmission may shift poorly or erratically.
  • Additionally, the engine may emit unusual noises or vibrations, and the vehicle may experience difficulty starting or fail to start altogether.

The automobile fault code p2607 can be caused by a range of issues, including a faulty IAH relay and poor electrical connections.

  • The automobile fault code P2607 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 automobile fault code p2607, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2607, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 P2607 indicates a problem with the intake air heater system. The diagnosis involves checking the wiring, connectors, and the heater relay.

The fixing cost is influenced by the estimated repair time, which is 1.0 hour. The cost of repair varies between $75 and $150 per hour, depending on the auto repair shop. Other factors that may affect the fixing cost include the cost of replacement parts, the complexity of the repair, and the location of the repair shop.

The P2607 code refers to the Intake Air Heater ‘B’ Circuit Low. 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 powered by the battery positive voltage circuit through the IAH relay.

What are the possible causes of the P2607 automobile fault code?

If you notice the engine light ON or Service Engine Soon Warning Light, it could be due to the P2607 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.
