2021 Ram Promaster Window Van Check Engine Light Codes

The 2021 Ram Promaster Window Van commonly reports codes related to emissions components, oxygen sensors (P0130–P0167 range), evaporative system leaks (P0440 series), and misfire codes (P0300 series). Left unaddressed, these codes can reduce fuel economy, damage catalytic converters, and increase repair costs substantially. For example, a persistent oxygen sensor fault can lead to poor fuel trim and eventual catalytic converter failure — an expensive replacement compared to the modest cost of an O2 sensor. Evaporative system leaks can cause failed emissions tests and repeated service visits if ignored. At Larry H. Miller Chrysler Jeep Dodge Ram Boise, our certified techs use OEM diagnostic routines to pinpoint the root cause and present repair options with clear pricing and long-term savings explained. We combine quick diagnostics, factory parts, and warranty protection to lower lifecycle costs. To get started, schedule service and ask about current service specials that reduce your out-of-pocket expense.
