1. 1

   Inspect

   Check the wiring and connections to the manifold air temperature sensor for damage, corrosion, or loose contacts.

2. 2

   Measure

   Use a multimeter to measure the resistance of the manifold air temperature sensor and compare it to the manufacturer's specifications.

3. 3

   Replace

   If the resistance is out of range, replace the manifold air temperature sensor with a new one that meets the required specifications.
