P0658 Fault in 2008 Ford Expedition: Symptoms and Diagnosis

Model: 2008 Ford Expedition Fault Code: P0658 Posted: 2021-01-04 11:53

A 2008 Ford Expedition owner is experiencing a P0658 diagnostic trouble code. When this fault appears, fuel efficiency significantly decreases, requiring more aggressive use of the gas pedal—especially when starting from a stop. Shifting from reverse to drive or any gear change results in rough transitions, vehicle shaking, and harsh shifting sensations. The P0658 code is related to the transmission control module's sensor reading for the transmission input speed signal, and this issue may indicate a faulty sensor or wiring problem affecting shift performance and fuel economy.
