P2436 Dodge Code - Secondary Air Injection System Air Flow/Pressure Sensor Circuit Range/Performance Bank 2
Quick Answer
The Secondary Air Injection (AIR) System aids in the reduction of hydrocarbon exhaust emissions during a cold start-up. Common causes include Faulty AIR Pressure Sensor, AIR Pressure Sensor harness is open or shorted, AIR Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2436 Dodge Description
The Powertrain Control Module (PCM) activates the AIR system by simultaneously supplying grounds to the AIR pump and the AIR valve relays. This action closes the relays' internal contacts. The AIR pump and the AIR control solenoid valve/pressure sensor assembly are in turn energized, the pump runs and the control/shut-off valve opens.
The AIR pump sends pressurized fresh air into the pipes/hoses through the open control/shut-off valve, and into the exhaust manifold. The extra air accelerates the catalyst operation, helping it to reach operating temperature faster. The AIR pump remains ON for a short period of time after the control/shut-off valve is commanded OFF. When the AIR pump is commanded OFF it will not run or be activated until the next vehicle start. When the AIR system is inactive, the closed AIR control/shut-off valve prevents air/exhaust flow in either direction.
The AIR system pressure sensor is used to monitor pressure at the AIR control solenoid valve/pressure sensor assembly inlet during the commanded ON/OFF states.

What are the common symptoms of code P2436 in a Dodge?
Symptoms may include an illuminated check engine light, reduced engine performance, poor fuel efficiency, or a failed emissions test.
What causes the P2436 code in a Dodge?
Common causes include a faulty air injection pressure sensor, damaged wiring or connectors, a malfunctioning secondary air injection pump, or an obstruction in the air injection system.
How do I diagnose the P2436 code on my Dodge?
Start by using an OBDII scanner to confirm the code, inspect the air injection pressure sensor and wiring for damage, and check for obstructions or malfunctions in the secondary air injection system.
Can I drive my Dodge with the P2436 code?
While the vehicle may still be drivable, it is not recommended to ignore this code as it can lead to increased emissions and possibly further damage to the secondary air injection system.
How can I fix the P2436 code on a Dodge?
