OBD-II Trouble Code Description for P0052 Porsche
HO2S Heater Control Circuit High
What does this mean?
OBD2 Code P0052 Porsche definition:
A P0052 Porsche DTC (diagnostic trouble code) definition:the O2 sensor (oxygen sensor) located on Bank 2 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2. Bank 2 is the side of the engine that doesn’t contain cylinder #1. This O2 sensor #1 may also be refered to as an air/fuel ratio sensor since on some vehicles it is. The sensor detects the amount of oxygen in the exhaust gas compared to the outside air and then vehicle’s computer adjusts the air/fuel ratio going into the engine. The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the O2 sensor. Essentially this P0052 Porsche code means that the resistance of the heater circuit is higher than normal. In some cases, that resistance level must be higher than 10 A to trigger the DTC code. Note, this code is very similar in nature to P0031 Porsche, P0032 Porsche, and P0051 Porsche
Symptoms
Possible sumptoms of OBD code P0052 Porsche
Most likely you’ll not notice any symptoms other than the MIL (malfunction indicator lamp, a.k.a. the check engine light) will illuminate.
Causes
Possible causes of OBD code P0052 Porsche
A P0052 Porsche DTC trouble code may be caused by one or more of the following: A short in the heater circuit in the sensor A failed O2 sensor heater Wiring/connectors broken/frayed leading to sensor and/or relay Failed PCM/ECM
Possible Solutions
To fix a P0052 Porsche DTC code, you’ll need to do a proper diagnosis. To do that, you’ll want to inspect the wiring and connectors leading to the sensor. Also if equipped with a heater relay and fuse, you’ll want to check those as well. Use a digital volt ohm meter to: check for 12 volts at the heater circuit feed (hint: unplug the sensor and check at the wiring connector to do this measurement) check the ground circuit for continuity measure the resistance of the heater circuit (done on the sensor itself) measure the resistance and voltage of the wiring Refer to a service manual for the correct specifications (volts, ohms) for your vehicle. On some Toyota vehicles this code is triggered when the resistance of the heater circuit is above 10 A. With that said, a common fix for this DTC is to replace the air/fuel (O2 oxygen) sensor #2 on bank 1. Please keep in mind that OEM (original equipment) replacement sensors are recommended (from the dealer). Aftermarket sensors can be less reliable and of poorer quality (not always, but more often). There’s also a chance that replacement parts for the P0052 Porsche code may also fall under a federal emissions warranty (check with your dealer to see if it’s covered).

2. Look up the other OBD II Trouble Codes, please use the search box. Enter the 5 character trouble codes in the search box and submit the search.
3. Don’t assume a particular OBD-II code means the same for other auto manufacturers as there are many makes specific codes in use.
4. If your OBD-II trouble codes are for a different car, select that vehicle series before searching for the diagnostic codes because not all OBD2 codes used by one manufacture are used by the other makes.
