P0057 Chrysler Code - O2 Sensor 2/2 Heater Circuit Low
Quick Answer
Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. Common causes include Faulty Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2, Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 harness is open shorted, Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0057 Chrysler Description
In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.
The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
What are the Possible Causes of the DTC P0057 Chrysler?
- Faulty Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 harness is open shorted
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 circuit poor electrical connection
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0057 Chrysler?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0057 Chrysler Code
1. What does the OBDII code P0057 mean on a Chrysler?
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.
