P1297 Mitsubishi Code - No Change In MAP From Start To Run
Quick Answer
The P1297 code in a Mitsubishi indicates that there has been no change in the manifold absolute pressure (MAP) sensor reading from the moment the engine is started to when it transitions to running. Common causes include Faulty MAP sensor, Vacuum leak in the intake manifold, Wiring or connector issues in the MAP sensor circuit. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1297 Mitsubishi Description
The P1297 code in a Mitsubishi indicates that there has been no change in the manifold absolute pressure (MAP) sensor reading from the moment the engine is started to when it transitions to running. The MAP sensor is a crucial component in the engine management system, as it measures the pressure inside the intake manifold and provides this information to the engine control module (ECM). This data is used to calculate the air-fuel ratio, ignition timing, and other parameters necessary for optimal engine performance.
Common Causes of P1297 Mitsubishi
- Faulty MAP sensor
- Vacuum leak in the intake manifold
- Wiring or connector issues in the MAP sensor circuit
- ECM software malfunction
- Intake manifold gasket failure
Symptoms of P1297 Mitsubishi
- Decreased engine power
- Rough idling or stalling
- Poor acceleration
- Reduced fuel economy
- Check Engine Light illuminated
How to Fix P1297 Mitsubishi
- Begin by inspecting the MAP sensor and its wiring for any visible damage or corrosion. Replace the sensor if necessary.
- Check for any vacuum leaks in the intake manifold and repair them accordingly.
- Inspect the wiring and connectors in the MAP sensor circuit for any loose connections or shorts. Repair or replace any damaged components.
- Perform a diagnostic scan to reset the ECM and clear the fault code. Monitor the MAP sensor readings to ensure they change appropriately when the engine is started.
- Test drive the vehicle to verify that the issue has been resolved and that the engine performance has returned to normal.
Cost to Fix P1297 Mitsubishi
The cost of repairing a P1297 code in a Mitsubishi can vary depending on the specific cause of the issue. On average, the cost of replacing a faulty MAP sensor can range from $100 to $200, including parts and labor. However, if the issue is more complex, such as a vacuum leak or ECM malfunction, the repair costs could be higher. It is recommended to consult with a professional mechanic to get an accurate estimate based on the specific diagnosis and repair needed. Labor rates at auto repair shops typically range from $80 to $150 per hour, but can be higher in metropolitan areas or at dealerships.

Frequently Asked Questions about P1297 Mitsubishi Code
1. What does the OBDII code P1297 mean on a Mitsubishi?
P1297 indicates "No Change in MAP From Start To Run," meaning the Manifold Absolute Pressure (MAP) sensor isn't detecting the expected change in pressure after the engine starts.
2. What are the common symptoms of code P1297 in a Mitsubishi?
Symptoms include poor engine performance, stalling, lack of power, rough idling, and possible illumination of the check engine light.
3. What causes the P1297 code on a Mitsubishi?
The code can be caused by a faulty MAP sensor, vacuum leaks, intake manifold issues, wiring problems, or a malfunctioning ECU.
4. Can a vacuum leak trigger the P1297 code?
Yes, a vacuum leak can prevent the correct pressure change in the intake manifold, which can cause the P1297 code.
5. How do I diagnose the P1297 code on my Mitsubishi?
Start by checking the MAP sensor and its wiring for damage or loose connections. Inspect for vacuum leaks and ensure the intake manifold and throttle body are working properly.
6. Can I still drive my Mitsubishi with a P1297 code?
Driving with a P1297 code is not recommended, as it can result in poor performance, increased fuel consumption, and potential engine damage.
7. How do I fix the P1297 code on a Mitsubishi?
Repairs may include replacing the MAP sensor, repairing vacuum leaks, fixing intake manifold issues, or addressing wiring or ECU problems.
8. How can I test the MAP sensor for a P1297 code?
Use a multimeter to check the MAP sensor's voltage output and compare it to the manufacturer’s specifications while monitoring for changes as engine conditions vary.
9. How much does it cost to fix a P1297 code?
Repair costs vary, but replacing a MAP sensor typically ranges from $100 to $300, while fixing vacuum leaks or wiring issues may cost less or more depending on the complexity.
10. Can a bad ECU cause the P1297 code?
Yes, a malfunctioning ECU can fail to process MAP sensor data correctly, leading to the P1297 code, though this is less common than sensor or vacuum issues.
