Code P0057 Chrysler Description
The P0057 Chrysler code specifically refers to an issue with the O2 sensor 2/2 heater circuit being detected as low. This means that the heating element within the oxygen sensor located downstream of the catalytic converter is not functioning properly. The O2 sensor plays a crucial role in measuring the oxygen levels in the exhaust gases, which helps the engine control module adjust the air-fuel mixture for optimal combustion. If the heater circuit is not working as intended, it can lead to inaccurate readings and potentially affect the vehicle's performance and emissions output. Ignoring this issue can result in decreased fuel efficiency, reduced engine performance, and potential damage to the catalytic converter over time.
Common Causes of P0057 Chrysler
- Faulty O2 sensor heater element
- Wiring or connector issues in the O2 sensor circuit
- Blown fuse related to the O2 sensor heater circuit
- Engine coolant leak affecting the O2 sensor
- Internal PCM (powertrain control module) failure
Symptoms of P0057 Chrysler
- Check engine light illuminated on the dashboard
- Decreased fuel efficiency
- Rough idling or stalling
- Failed emissions test
- Increased emissions output
How to Fix P0057 Chrysler
- Diagnose the specific cause of the issue using a diagnostic scanner and multimeter
- Inspect the O2 sensor wiring and connector for any damage or corrosion
- Test the O2 sensor heater element resistance and replace if necessary
- Check and replace any blown fuses related to the O2 sensor heater circuit
- Clear the fault code and perform a test drive to ensure the issue is resolved
Cost to Fix P0057 Chrysler
The typical repair costs for addressing a P0057 Chrysler code can range from $150 to $400, depending on the specific cause of the issue and the labor rates in your area. This estimate includes the cost of a new O2 sensor, any necessary wiring repairs, and labor charges. Keep in mind that prices may vary based on the vehicle's make and model, as well as the location and type of repair shop you choose. Be sure to get quotes from multiple shops to find the best deal.

P0057 indicates a problem with the oxygen sensor heater circuit for Bank 2, Sensor 2, where the heater control circuit is reading a low voltage.
2. What are the symptoms of the P0057 code on a Chrysler?
Symptoms may include an illuminated check engine light, decreased fuel efficiency, and possibly rough idling or poor engine performance.
3. What causes the P0057 code on a Chrysler?
Common causes include a failed oxygen sensor, a blown fuse, wiring issues such as short circuits or damaged connectors, or a malfunctioning powertrain control module (PCM).
4. Which oxygen sensor is affected by the P0057 code on a Chrysler?
The code refers to the downstream oxygen sensor (Sensor 2) on Bank 2, which is typically located after the catalytic converter on the side of the engine opposite Cylinder 1.
5. Can I drive my Chrysler with the P0057 code?
While it may be possible to drive the vehicle, it is not recommended as it can lead to reduced fuel efficiency and possible damage to the catalytic converter over time.
6. How do I fix the P0057 code on my Chrysler?
Repairs may include replacing the faulty oxygen sensor, fixing damaged wiring or connectors, replacing a blown fuse, or addressing issues with the PCM if necessary.
7. How do I diagnose the P0057 code on a Chrysler?
Diagnosis typically involves using a scan tool to confirm the code, inspecting the wiring and connectors for damage, checking the fuse for the oxygen sensor heater circuit, and testing the sensor itself for proper resistance.
8. How much does it cost to fix the P0057 code on a Chrysler?
Repair costs depend on the exact issue but generally range from $100 to $400, with the oxygen sensor replacement typically costing $150 to $300 including parts and labor.
9. Can a bad oxygen sensor cause other problems in my Chrysler?
Yes, a bad oxygen sensor can lead to poor engine performance, increased emissions, and potential damage to the catalytic converter if not addressed.
10. What tools do I need to fix the P0057 code on my Chrysler?
You’ll need an OBDII scan tool, a multimeter for testing electrical connections, basic hand tools for removing and replacing the sensor, and potentially a wiring diagram for troubleshooting.
