Frequently Asked Question

Cause:

1. The carburetor temperature probe is primarily measuring the temperature of the body of the carburetor. Carburetor heat will warm the body of the carburetor slowly, so it may take many seconds for a small change to be observed.
2. The carburetor temperature probe is not mounted in the carburetor.

Troubleshooting:

1. Allow sufficient time for the carburetor heat to warm the carburetor when testing.
2. Visually verify the sensor is mounted in the carburetor.
