Code P22AB Dodge Description
The P22AB diagnostic trouble code (DTC) for Dodge vehicles indicates an issue with the O2 sensor Bank 1 Sensor 2 positive current control circuit being open. This means that there is an interruption in the circuit that controls the current flow for the downstream oxygen sensor located after the catalytic converter on the bank 1 side of the engine. The O2 sensor plays a crucial role in monitoring the oxygen levels in the exhaust gases, providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion.
Common Causes of P22AB Dodge
- Wiring or connector damage
- Corrosion in the circuit
- Electrical faults in the ECM
- Sensor malfunction
- Poor quality fuel
Symptoms of P22AB Dodge
- Decreased fuel efficiency
- Engine misfires or hesitation
- Illumination of the check engine light
- Rough idling or stalling
- Increased emissions
How to Fix P22AB Dodge
- Begin by conducting a thorough visual inspection of the wiring and connectors related to the O2 sensor Bank 1 Sensor 2 positive current control circuit.
- Test the circuit using a multimeter to check for continuity and proper voltage levels.
- Replace any damaged wiring, connectors, or the O2 sensor itself if necessary.
- Clear the DTC with a scan tool and perform a test drive to ensure the issue has been resolved.
- If the problem persists, further diagnostics may be required to pinpoint the exact cause of the open circuit.
Cost to Fix P22AB Dodge
The typical repair costs for addressing the P22AB DTC can vary depending on the extent of the issue and the specific components that need replacement. On average, the parts for this repair, including a new O2 sensor and any wiring or connectors, may range from $100 to $300. Labor costs can add an additional $100 to $200, with total repair expenses falling between $200 and $500.

2. What are the symptoms of code P22AB on a Dodge?
Common symptoms include the check engine light turning on, decreased fuel efficiency, poor engine performance, and possible difficulty passing emissions tests.
3. Which O2 sensor does P22AB refer to?
P22AB refers to the downstream oxygen sensor (Sensor 2) on Bank 1, which monitors the catalytic converter's efficiency.
4. What causes the P22AB code to appear?
Possible causes include a damaged O2 sensor, a broken or corroded wiring harness, a loose electrical connection, or a faulty engine control module (ECM).
5. Can I drive my Dodge with a P22AB code?
Driving with this code is possible but not recommended, as it could lead to reduced fuel efficiency and engine performance, and prolonged issues may damage the catalytic converter.
6. How do I diagnose a P22AB code on my Dodge?
Start by inspecting the O2 sensor wiring and connectors for damage or corrosion. Use a multimeter to test the circuit continuity and verify the sensor's functionality.
7. How do I fix a P22AB code on a Dodge?
Repairs might include replacing the O2 sensor, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the ECM if necessary.
8. How much does it cost to fix a P22AB code?
The repair cost varies; replacing an O2 sensor typically costs $150-$400, while fixing wiring issues or replacing the ECM could be more expensive.
9. What tools are needed to repair a P22AB code?
You may need an OBDII scanner, a multimeter, basic hand tools, and potentially an O2 sensor socket for removal and installation.
10. Can a P22AB code be cleared without repair?
Clearing the code without addressing the underlying issue may temporarily turn off the check engine light, but the problem will likely return.
