Code P0237 Dodge Description
The P0237 diagnostic trouble code (DTC) in a Dodge vehicle indicates that the Manifold Absolute Pressure (MAP) sensor has detected a high voltage input for an extended period. The MAP sensor is a crucial component that measures the pressure within the intake manifold and sends this information to the engine control module (ECM) for fuel and ignition system adjustments. When the MAP sensor reads a voltage that is too high for an extended period, it can lead to various performance issues in the vehicle.
Common Causes of P0237 Dodge
- Faulty MAP sensor
- Wiring or connector issues
- Vacuum leaks in the intake system
- ECM malfunction
- Intake manifold issues
Symptoms of P0237 Dodge
- Reduced engine power
- Poor fuel efficiency
- Rough idling
- Hesitation or stalling during acceleration
- Engine misfires
How to Fix P0237 Dodge
- Perform a thorough inspection of the MAP sensor, wiring, and connectors for any visible damage or corrosion.
- Check for vacuum leaks in the intake system and repair or replace any damaged components.
- Test the MAP sensor using a multimeter to ensure it is functioning within the specified voltage range.
- If the MAP sensor is faulty, replace it with a new one and reset the DTC using a diagnostic tool.
- Clear any remaining codes and perform a test drive to confirm that the issue has been resolved.

Frequently Asked Questions about P0237 Dodge Code
1. What does the OBDII code P0237 mean on a Dodge vehicle?
P0237 indicates that the Engine Control Module (ECM) has detected a low voltage signal from the MAP (Manifold Absolute Pressure) sensor, which is interpreted as a "too high too long" condition.
2. What are common symptoms of the P0237 code in a Dodge?
Symptoms may include poor engine performance, reduced power, rough idling, black smoke from the exhaust, and potentially triggering the check engine light.
3. What causes the P0237 code to appear in Dodge vehicles?
Common causes include a faulty MAP sensor, wiring issues such as shorts or open circuits, vacuum leaks, or a defective ECM.
4. Can a dirty air filter cause the P0237 code in a Dodge?
While unlikely, a severely clogged air filter can indirectly contribute to MAP sensor issues by affecting airflow, but it’s not a primary cause of the P0237 code.
5. How do I diagnose a P0237 code in my Dodge?
Start by inspecting the MAP sensor and its wiring for damage or disconnections, check for vacuum leaks, and use a multimeter to test the voltage signal from the sensor.
6. Can I drive my Dodge with a P0237 code?
It’s not recommended to drive long distances with this code, as it can lead to poor engine performance, reduced fuel efficiency, and potential engine damage.
7. How do I fix the P0237 code in a Dodge vehicle?
Repairs may include replacing the MAP sensor, repairing faulty wiring, fixing vacuum leaks, or reprogramming/updating the ECM if necessary.
8. How much does it cost to repair a P0237 code in a Dodge?
The cost can range from $50 to $300, depending on whether the MAP sensor needs replacement or if other issues like wiring repairs are involved.
9. Can a bad MAP sensor cause the P0237 code?
Yes, a malfunctioning MAP sensor is one of the most common causes of the P0237 code.
10. Does clearing the P0237 code solve the problem in a Dodge?
Clearing the code will reset the check engine light temporarily, but the underlying issue must be fixed to prevent the code from returning.
