Common check-engine codes on the Dodge Grand Caravan
2008-2020
Grand Caravans from 2011 on use the 3.6L Pentastar V6, so they share its oil filter housing and oil pressure sensor problems. EVAP leaks and electrical module codes are also common.
Most common: P0520, P0456, P0300, P0420, P0562, P0700.
Known problems on the Dodge Grand Caravan
P0520 Engine Oil Pressure Sensor/Switch "A" Circuit
P0520 means the engine computer isn't getting a usable signal from the oil pressure sensor; check the oil level before assuming it's just the sensor.
On the Dodge Grand Caravan: On the 3.6L, the plastic oil filter housing often leaks and soaks the oil pressure sensor in it; replace both together.
P0520: causes, can I keep driving, and what to check first →
P0456 Evaporative Emission System Leak Detected (Very Small Leak)
P0456 means the EVAP system has a very small leak, often a gas cap that isn't sealing perfectly.
On the Dodge Grand Caravan: EVAP very small leaks: gas cap, EVAP hoses and leak detection parts near the tank.
P0456: causes, can I keep driving, and what to check first →
P0300 Random/Multiple Cylinder Misfire Detected
P0300 means the engine is misfiring in more than one cylinder, often from worn plugs or coils, a vacuum leak or low fuel pressure.
On the Dodge Grand Caravan: Misfires: plugs and coils; early 3.6L engines had a known valve problem on some cylinders, so check for bulletins.
P0300: causes, can I keep driving, and what to check first →
P0420 Catalyst System Efficiency Below Threshold (Bank 1)
P0420 means the catalytic converter on bank 1 isn't cleaning the exhaust well enough, usually a worn converter, an exhaust leak or a lazy oxygen sensor.
On the Dodge Grand Caravan: Catalyst efficiency at higher mileage.
P0420: causes, can I keep driving, and what to check first →
P0562 System Voltage Low
P0562 means the electrical system voltage is too low, usually a failing alternator, weak battery or bad connection.
On the Dodge Grand Caravan: Low system voltage: weak batteries and charging problems can set many module codes at once; test the battery and alternator.
P0562: causes, can I keep driving, and what to check first →
P0700 Transmission Control System (MIL Request)
P0700 means the transmission computer has stored its own fault code; read the transmission codes to find the real problem.
On the Dodge Grand Caravan: Transmission fault flag on the 6-speed automatic; read the transmission codes.
P0700: causes, can I keep driving, and what to check first →
