P0052 JEEP - O2 Sensor 2/1 Heater Circuit High
P0052 JEEP Possible Causes
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 1 harness is open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 1 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 2 Sensor 1
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 1 circuit fuse
- Faulty Engine Control Module (ECM)
First diagnose P0052 JEEP code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
Cost of diagnosing the P0052 JEEP code
Labor: 1.0The cost of diagnosing the P0052 JEEP code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the P0052 JEEP code detected?The P0052 is set when the ECM detects an excessively high voltage through the heated oxygen sensor heater circuit
P0052 JEEP Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0052 Jeep DescriptionOxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).
In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.
The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
