Guide to the 2006-2010 Chrysler Sebring EVAP Leak Detection Pump
If you have a check engine light and EVAP codes like P0456 or P0457, this guide is for your Sebring.
- A lit check engine light with codes P0456 or P0457 is the primary symptom of a failing leak detection pump.
- First, check that your gas cap is tight and the seal is not cracked before replacing any parts.
- Aftermarket brands like Dorman and Standard Ignition are affordable and reliable for this repair.
- This is a simple DIY replacement that can be done in under an hour with basic tools.
Is Your Check Engine Light On? It Could Be the EVAP Leak Detection Pump

A common reason for the check engine light in a 2006-2010 Chrysler Sebring is a problem with the Evaporative Emissions (EVAP) system. The system's leak detection pump is often the cause. This part, also called an Evaporative System Integrity Module (ESIM), is responsible for testing your fuel system for vapor leaks. When it fails, your car can't verify that the system is sealed, which turns on the light and prevents you from passing an emissions test.
Common OBD-II Codes
If your leak detection pump is failing, you will likely see one or more of these diagnostic trouble codes:
- P0456: A very small leak has been detected.
- P0457: A leak has been detected, often interpreted as a loose or missing gas cap. 🎬 Watch this guide on diagnosing and fixing P0457 codes.
- P0440: A general EVAP system failure.
- P1494: A fault with the leak detection pump's switch or mechanical parts. 🎬 See how to test the Sebring EVAP system for leaks.
While a loose gas cap is the most common cause for these codes, a faulty pump is the next likely culprit if tightening or replacing the cap doesn't solve the problem.
Choosing the Right Aftermarket Part: Dorman vs. Standard Ignition

For the 2006-2010 Sebring, you don't need to buy an expensive OEM part from the dealer. Aftermarket brands offer a direct-fit replacement that works just as well for a fraction of the price. The two main brands you'll find are Dorman and Standard Ignition (often sold under store brands like Carquest).
- Dorman: Dorman is a well-known aftermarket manufacturer. Their leak detection pumps are widely available and are described as direct replacements made from quality materials. Reviews for similar Dorman parts are generally positive, with many customers reporting that the part fixed their check engine light and "gascap" warning message.
- Standard Ignition / Carquest: Standard is another reputable brand. Their parts are also designed to be direct-fit replacements that meet or exceed OEM specifications.
Pro Tip: Both Dorman and Standard Ignition are reliable choices for this specific part. Quality is comparable, so your decision can be based on price and availability. Both are engineered to match the original's fit and function.

Frequently Asked Questions

Where is the leak detection pump on a 2006-2010 Chrysler Sebring?
The leak detection pump is located on top of the charcoal canister. You can find the canister near the fuel tank, typically on the passenger side, under the vehicle. It looks like a small, mushroom-shaped plastic component with electrical and hose connections.
Is this a difficult repair to do myself?
No, this is a relatively easy DIY repair for someone with basic tools. It involves raising the rear of the vehicle, locating the pump on the charcoal canister, disconnecting the electrical connector and hose, and twisting the old pump off. The new one twists on in its place. 🎬 Watch a teardown to see how the pump works internally. The job typically takes less than an hour.
Is a leak detection pump the same as a purge valve?
No, they are different parts of the EVAP system. The leak detection pump tests the system for leaks, while the purge valve (or purge solenoid) is located in the engine bay and opens to allow stored fuel vapors to be burned by the engine.
Are there any recalls for this part?
No, there are no specific recalls on the EVAP leak detection pump for the 2006-2010 Chrysler Sebring. Searches of the NHTSA database show recalls for other issues like airbags and power steering, but not for the EVAP pump.
