P0522 on Jeep by model: symptoms, diagnosis and fix
Polishing-tape debris left in the balance shaft module bearings during engine manufacture circulates in the oil and can starve the engine of oil pressure. FCA recalled 2014 Jeep Patriot and Compass (and 2013 Chrysler 200 / Dodge Avenger) 2.4L vehicles under its own campaign N52, NHTSA 13V552000. The failure presents as a low-oil-pressure warning followed by stalling; left unaddressed it can destroy bearings and the engine. This is specific to the 2.4L ED3 World Engine in the 2014 build window and is NOT a defect of every Patriot engine year.
Common Symptoms
- Oil pressure warning light
- Engine stalls without warning
- Knocking or rumble from lower engine
- Metallic debris in oil or on drain plug
- Engine will not restart after stall
How to Fix
Check the VIN at nhtsa.gov/recalls. If the vehicle is in the 13V552000 population the dealer replaces the balance shaft module free of charge, regardless of age or mileage. If the recall was already performed, a low-oil-pressure light on a 2.4L should be diagnosed with a mechanical gauge before assuming the sensor is wrong - the balance shaft module and oil pump pickup are the usual mechanical culprits. Outside the recall population, balance shaft module replacement runs roughly $700-$1,400 in parts and labor because the oil pan and pickup must come off.

Frequently asked questions
What does P0522 mean on a Jeep?
P0522 stands for "Engine Oil Pressure Sensor/Switch Low Voltage." This code means the engine oil pressure sensor is sending a voltage that is lower than the normal operating range. Depending on how the sensor is wired, this can indicate either a wiring/sensor fault or genuinely low oil pressure. Because low oil pressure can quickly destroy an engine, the actual oil pressure should be verified with a mechanical gauge before assuming it's just an electrical issue. Watch for an oil warning light, ticking noises, or other signs of low pressure. On Jeep it is documented across 1 model: Patriot.
What are the most common causes of P0522?
The most common causes of P0522 are: Faulty oil pressure sensor/switch, Short to ground or low voltage in the sensor wiring, Genuinely low oil pressure or low oil level, Corroded or damaged connector at the sensor, Poor electrical ground, Failing oil pump, Use of incorrect oil viscosity. The specific cause varies by vehicle.
How much does it cost to fix P0522 on a Jeep?
Repair costs vary widely with the root cause and Jeep model; each issue on this page carries its own estimate where one is published.
