At Larry H. Miller Chrysler Dodge Jeep Ram 104th in Denver, Colorado, our team commonly sees several check engine codes on the 2020 Dodge Grand Caravan. Typical codes include P0300 (random/multiple cylinder misfire), P0420 (catalyst efficiency below threshold), P0171/P0174 (lean fuel trim), and P0442/P0455 (evaporative emissions leaks). Ignoring these codes can lead to progressively higher costs: misfires can damage spark plugs and the catalytic converter leading to repairs well into four figures; persistent oxygen sensor faults reduce fuel economy and cause failed emissions tests; EVAP leaks can lead to failed inspections and drivability complaints. Our service process begins with a precise scan and a clear estimate, so you know what to expect.
