Chrysler Error Code P1297: How to Fix It

Q: What causes Chrysler P1297 error code?

P1297 is typically caused by a faulty MAP sensor, damaged vacuum lines, loose electrical connections, or vacuum leaks in the intake system that prevent the MAP sensor from detecting proper pressure changes.

Q: Can I drive with P1297 code?

While you can drive short distances with P1297, it's not recommended for extended driving. The error can cause poor fuel economy, rough idling, hesitation, and potential engine damage if left unrepaired.

Q: How much does it cost to fix P1297?

Repair costs vary depending on the root cause. A new MAP sensor typically costs $30-80, vacuum lines cost $10-20, while professional diagnosis and labor can add $100-200 to the total repair cost.

Q: Where is the MAP sensor located on Chrysler vehicles?

The MAP sensor is usually mounted directly on the intake manifold or connected to it via a vacuum line. Common locations include near the throttle body or on the firewall side of the intake manifold.

Q: Will P1297 cause my car to fail emissions testing?

Yes, P1297 will likely cause your vehicle to fail emissions testing since it affects the air-fuel mixture and engine performance. The code must be resolved and the system must complete its readiness monitors before passing emissions.

Abstract

Chrysler error code P1297 indicates that the Manifold Absolute Pressure (MAP) sensor is not detecting the expected pressure changes between engine startup and normal running conditions. This can cause poor engine performance, rough idling, and reduced fuel economy.
