The automobile fault code P2437 indicates a problem with the secondary air injection system air flowpressure sensor circuit. The estimated repair time for this fault code 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 problem, the type of vehicle, and the location of the repair shop.

The P2437 code is related to the Secondary Air Injection (AIR) System. It indicates a problem with the air flowpressure sensor circuit on the bank of the engine with cylinder number one. The AIR system helps reduce hydrocarbon exhaust emissions during a cold start-up.

The system pumps pressurized fresh air into the exhaust manifold to accelerate the catalyst operation.

The AIR pump runs for a short period of time after start-up and remains off until the next vehicle start when inactive. The AIR system pressure sensor monitors pressure at the AIR control solenoid valvepressure sensor assembly inlet during the commanded ONOFF states.

What are the possible causes of the automobile fault code P2437?

If you see the engine light on or the service engine soon warning light, it could be due to the P2437 fault code. This code is usually caused by a faulty AIR Pressure Sensor, an open or shorted AIR Pressure Sensor harness, or a poor electrical connection in the AIR Pressure Sensor 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.

How can I visually inspect the related wiring harness and connectors to fix the P2437 fault code?

If you’re experiencing the P2437 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may need to visually inspect the related wiring harness and connectors. This fault code can be caused by a faulty AIR Pressure Sensor, an open or shorted AIR Pressure Sensor harness, or a poor electrical connection in the AIR Pressure Sensor circuit. To fix the issue, check the possible causes listed above and inspect the wiring harness and connectors for any damage or corrosion. Look for broken, bent, pushed out, or corroded connector’s pins.

What are the signs that the AIR Pressure Sensor circuit has a poor electrical connection causing the P2437 fault code?

If the AIR Pressure Sensor circuit has a poor electrical connection, it can cause the P2437 fault code. This is indicated by the Engine Light or Service Engine Soon Warning Light turning on. To fix this issue, check for a faulty AIR Pressure Sensor, an open or shorted harness, or a poor electrical connection. Visually inspect the wiring harness and connectors for any damage or corrosion, and check for broken, bent, pushed out, or corroded connector pins.
