Choosing dealership service guarantees OEM parts and factory procedures, ensuring repairs meet Ford standards and preserve warranties—note that warranty-covered repairs must be performed at a certified dealership.

2021 Ford Ranger Check Engine Light Codes

Common check engine light codes for the 2021 Ford Ranger include P0420 (catalyst system efficiency), P0171 (system too lean), P0300 (random/multiple misfires), and P0456 (EVAP small leak). Left unaddressed, P0420 can lead to costly catalytic converter replacement; P0171 and P0300 can cause reduced fuel economy, poor drivability, and potential engine damage; P0456 may be inexpensive to fix but can cause a persistent fault and failed emissions tests. Larry H. Miller Ford Mesa in Mesa, AZ, provides accurate diagnostics that identify these codes and prioritize repairs to avoid escalating costs. Our certified technicians explain each code, potential repair timelines, and the immediate versus long-term costs—showing how dealership service often costs less over time by preventing repeated shop visits, using OEM parts, and protecting warranty coverage. We also highlight convenience features such as quick turnarounds, comfortable waiting areas, and loaner options when available.
