🔧 1500 Classic - Mass Air Flow Sensor Replacement
Your 1500 Classic with the 3.6L V6 does not use a standalone MAF sensor from the factory. Air metering is handled by the intake air pressure/temp sensing system, so the part people often call the “MAF” is usually the sensor mounted in the intake tube or air inlet assembly. Replacing it is a quick job once the air intake duct is open.
Difficulty Level: Beginner | Estimated Time: 0.5-1 hours
⚠️ Safety & Precautions
- Park on level ground and set the parking brake.
- Let the engine cool before working around the intake tube.
- Disconnect the negative battery cable before unplugging the sensor.
