Were is the check engine light fuse on a 2007 dodge caliber?

There isn't a separate fuse specifically for the check engine light (MIL - Malfunction Indicator Lamp) on a 2007 Dodge Caliber. The check engine light is controlled by the Powertrain Control Module (PCM), and the PCM's power is controlled by several fuses. If your check engine light isn't working, the problem is much more likely to be with the PCM itself, a wiring issue, or a blown fuse in the main power circuits feeding the PCM, rather than a dedicated fuse for the light itself.

To troubleshoot a non-functioning check engine light, you should:

1. Consult your owner's manual: It will show you the location of the fuse box(es) (underhood and possibly inside the cabin) and a fuse diagram. Look for fuses related to the Powertrain Control Module (PCM), Engine Control Module (ECM), or similar. These are the fuses you should check.

2. Check the fuses: Carefully inspect the fuses listed above for any that are blown. Replace any blown fuses with fuses of the *same amperage*.

3. Have the vehicle scanned: If the fuses are okay, take your Caliber to an auto parts store (like AutoZone, Advance Auto Parts, etc.) and have them scan your vehicle's OBD-II system for diagnostic trouble codes (DTCs). This will pinpoint the problem. A non-functioning check engine light itself could be a code.

4. Professional diagnosis: If you're not comfortable troubleshooting electrical issues, take it to a qualified mechanic.

In short, there's no single "check engine light fuse" to look for; the issue is far more likely to be a broader electrical problem needing a professional diagnosis.
