Common check-engine codes on the Dodge Durango
2011-2023
The Durango uses the 3.6L Pentastar V6 or the 5.7L Hemi V8, so it shares their well-known problems: oil filter housing leaks and oil pressure sensor faults on the 3.6L, lifter and camshaft wear on the Hemi, and early 3.6L cylinder head valve problems.
Most common: P0520, P0300, P0456, P0420, P0128, P0562.
Known problems on the Dodge Durango
- Chrysler 3.6L Pentastar oil filter housing leak and oil pressure sensor (P0520, P0521)
- 5.7L Hemi lifter and camshaft wear ("Hemi tick") (P0300, P0301, P0302, P0303)
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 Durango: 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 →
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 Durango: On the 5.7L Hemi, a misfire with ticking points to lifter or cam wear. On 2011-2013 3.6L engines, misfires on cylinders 2, 4 or 6 can be the left cylinder head valve problem covered by Chrysler's extended warranty (bulletin D-14-12, 10 years/150,000 miles).
P0300: 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 Durango: 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 →
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 Durango: Catalyst efficiency, often with P0430: check for exhaust manifold leaks and misfires first.
P0420: causes, can I keep driving, and what to check first →
P0128 Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)
P0128 means the engine isn't reaching normal operating temperature, almost always a thermostat stuck open.
On the Dodge Durango: Thermostat stuck open; the 3.6L thermostat housing is plastic and can leak.
P0128: 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 Durango: Low system voltage can set many module codes at once; test the battery and alternator.
