Code P2250 Dodge Description
The P2250 diagnostic trouble code (DTC) for Dodge vehicles indicates an issue with the O2 sensor reference voltage circuit being too high on bank 2 sensor 1. This means that the oxygen sensor responsible for monitoring the air-fuel ratio in the exhaust system is not receiving the correct voltage signal. The O2 sensor reference voltage is crucial for accurate readings, which are used by the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion efficiency.
Common Causes of P2250 Dodge
- Faulty O2 sensor
- Wiring or connector issues in the O2 sensor circuit
- Malfunctioning ECM
- Power supply problems to the O2 sensor
- Exhaust leaks affecting O2 sensor readings
Symptoms of P2250 Dodge
- Decreased fuel efficiency
- Engine misfires or hesitation
- Rough idling or stalling
- Check Engine Light illuminated
- Increased emissions
How to Fix P2250 Dodge
- Use a diagnostic scanner to confirm the P2250 code and identify the specific O2 sensor causing the issue.
- Inspect the wiring and connectors in the O2 sensor circuit for any damage or corrosion. Repair or replace as necessary.
- Test the O2 sensor with a multimeter to check for proper voltage output. Replace the sensor if it is faulty.
- Clear the DTC and reset the ECM to see if the issue persists. Drive the vehicle to monitor for any reoccurrence of symptoms.
- If the problem persists, further diagnosis may be needed to identify any underlying ECM or power supply issues.
Cost to Fix P2250 Dodge
The typical repair costs for addressing a P2250 O2 Sensor Reference Voltage Circuit High Bank 2 Sensor 1 code can range from $200 to $500, depending on the specific cause of the issue and the cost of parts and labor. It is important to note that diagnostic time and labor rates can vary between auto repair shops, so it is recommended to obtain quotes from multiple sources for a more accurate estimate. Additionally, factors such as the vehicle's make and model, location, and engine type can also impact the overall repair costs.

Frequently Asked Questions about P2250 Dodge Code
What does OBDII code P2250 mean for a Dodge vehicle?
Code P2250 indicates a problem with the reference voltage circuit of the oxygen (O2) sensor on Bank 2 Sensor 1, specifically that the circuit voltage is too high.
What are the symptoms of code P2250 in a Dodge?
Common symptoms include poor fuel economy, rough idling, engine hesitation, reduced performance, and possibly an illuminated Check Engine Light.
What causes code P2250 in a Dodge?
Possible causes include a faulty O2 sensor, damaged wiring or connectors, a malfunctioning powertrain control module (PCM), or issues with the reference voltage circuit.
How can I diagnose code P2250 in a Dodge?
Start by inspecting the wiring and connectors near the O2 sensor for damage. Use a multimeter to test the reference voltage circuit and ensure the O2 sensor is functioning properly.
Can a faulty O2 sensor trigger code P2250?
Yes, a defective O2 sensor on Bank 2 Sensor 1 can cause this code to appear if it fails to regulate the reference voltage.
Is it safe to drive with code P2250 in a Dodge?
It may be safe to drive for short distances, but prolonged driving can lead to increased fuel consumption, engine performance issues, and potential damage to other components.
How do I fix code P2250 on a Dodge?
Repairs may include replacing the O2 sensor, repairing or replacing damaged wiring, or reprogramming or replacing the PCM if it's found to be faulty.
Can code P2250 be cleared without fixing the problem?
While the code can be cleared temporarily, it will likely return unless the underlying issue is resolved.
What tools are needed to troubleshoot code P2250?
You’ll typically need an OBDII scanner, a multimeter, and basic automotive tools to inspect and test the O2 sensor and wiring.
What is the role of Bank 2 Sensor 1 in a Dodge’s engine system?
Bank 2 Sensor 1 is the upstream oxygen sensor responsible for monitoring the air-fuel mixture before the catalytic converter on the side of the engine opposite Bank 1.
