2020 Ford Transit Cargo Van Check Engine Light Codes

Common check engine light codes for a 2020 Ford Transit Cargo Van include P0300 (random/multiple misfire), P0420 (catalyst efficiency below threshold), P0171 (system too lean), and P0135 (O2 sensor heater circuit). Left untreated, P0300 can lead to rough running, reduced fuel economy, and catalytic converter damage; repair costs can range from modest ignition repairs to several hundred dollars for exhaust components. P0420 often signals catalytic issues — delaying repair may result in a large repair bill for converter replacement. P0171 and O2 sensor faults sap fuel economy and can accelerate component wear. At Herb Chambers Ford of Braintree, we combine rapid diagnostics with OEM components to fix these issues correctly the first time, saving you immediate and long-term costs. Our service advisors outline options, warranty applicability, and financing choices so you can make an informed decision.
