P2436 Dodge Code - Secondary Air Injection System Air Flow/Pressure Sensor Circuit Range/Performance Bank 2
Quick Answer
The P2436 diagnostic trouble code (DTC) for Dodge vehicles specifically indicates a problem within the Secondary Air Injection System Air Flow/Pressure Sensor Circuit on Bank 2. Common causes include Faulty Sensor: The air flow/pressure sensor in the secondary air injection system may be malfunctioning, causing the ECM to detect a range/performance issue, Wiring Issues: Damage to the wiring harness that connects the sensor to the ECM can also trigger this code, Air Pump Failure: Problems with the air pump not delivering the correct amount of air into the exhaust stream can lead to a P2436 code. 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 P2436 diagnostic trouble code (DTC) for Dodge vehicles specifically indicates a problem within the Secondary Air Injection System Air Flow/Pressure Sensor Circuit on Bank 2. This code is typically triggered when the Engine Control Module (ECM) detects a range/performance issue in the sensor circuit for the secondary air injection system. The secondary air injection system is responsible for reducing emissions by introducing fresh air into the exhaust stream to help burn off any remaining fuel vapors.
Common Causes of P2436 Dodge
- Faulty Sensor: The air flow/pressure sensor in the secondary air injection system may be malfunctioning, causing the ECM to detect a range/performance issue.
- Wiring Issues: Damage to the wiring harness that connects the sensor to the ECM can also trigger this code.
- Air Pump Failure: Problems with the air pump not delivering the correct amount of air into the exhaust stream can lead to a P2436 code.
- Vacuum Leaks: Any leaks in the vacuum lines connected to the system can affect the air flow/pressure and trigger this code.
Symptoms of P2436 Dodge
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Reduced Power: The vehicle may go into a reduced power mode to prevent engine damage, resulting in decreased acceleration and overall performance.
- Rough Idling: The engine may idle roughly or inconsistently due to the incorrect air/fuel mixture caused by the secondary air injection system issue.
- Increased Emissions: If the secondary air injection system is not functioning properly, it can lead to increased emissions output from the vehicle.
How to Fix P2436 Dodge
- Diagnose the Issue: Use a scan tool to retrieve the specific DTC and further diagnose the problem within the secondary air injection system.
- Inspect Wiring: Check the wiring harness for any damage or loose connections that may be causing the sensor circuit range/performance issue.
- Test Sensor: Test the air flow/pressure sensor to determine if it is functioning correctly or needs to be replaced.
- Check Air Pump: Inspect the air pump for any signs of failure or malfunctions that could be affecting the system's performance.
- Clear Codes: After repairing the issue, clear the DTC and test drive the vehicle to ensure the problem has been resolved.
Cost to Fix P2436 Dodge
