2021 Ram Promaster City Check Engine Light Codes

At Larry H. Miller Dodge RAM FIAT Tucson we frequently see several common codes on the 2021 Ram Promaster City: P0456 (evaporative system small leak), P0420 (catalyst efficiency), P0300 (random/multiple cylinder misfire), and various O2 sensor codes. Each carries cost and risk if unaddressed—small EVAP leaks may only need a cap or seal but left alone can trigger emissions test failures; oxygen sensor faults degrade fuel economy and, if prolonged, harm the catalytic converter which is costly to replace. Misfires (P030x) can cause immediate engine damage and can escalate repair costs significantly. Our Tucson-based service team explains these codes clearly, shows inspection results, and recommends OEM repairs that prioritize long-term savings and reliability. We often outperform independent shops on overall value because accurate diagnostics prevent unnecessary parts changes and repeat labor.
