The automobile fault code P2609 relates to the issue of the engine control module (ECM) detecting a fault in the transmission fluid pressure sensor circuit. The estimated repair time for this fault is 1.0 hour.

The cost of fixing this fault is influenced by the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.

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

The P2609 code refers to the Intake Air Heater (IAH) system performance. The Engine Control Module (ECM) uses the 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 P2609 automobile fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P2609 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.
