P0158 O2 Sensor Circuit High Voltage
P0158 O2 Sensor Circuit High Voltage. The o2 sensor could be functioning improperly, or there could be a lack of continuity in the wiring to the ecu, or it is possible that power is not supplying sufficient enough voltage to the sensor. The p0158 code is set when the engine control module (ecm) detects that the rear o2 sensor signal voltage remains excessively high for an extended period of time.
O2 sensor 2/2 circuit high description: Sensor 1 or sensor 2 refers to the sensor’s. Two wires are dedicated to the heating element and two wires are dedicated to the sensor.
Start The Engine And Observe The Bank 2 Sensor 2 O2 Sensor Voltage.
If the voltage is high (approx. P0158 is a diagnostic trouble code (dtc) for 02 sensor circuit high voltage (bank 2, sensor 2). The code is triggered when:
O2 Sensor 2/2 Circuit High Description:
The o2 sensor could be functioning improperly, or there could be a lack of continuity in the wiring to the ecu, or it is possible that power is not supplying sufficient enough voltage to the sensor. The p0158 code is set when the engine control module (ecm) detects that the rear o2 sensor signal voltage remains excessively high for an extended period of time. Our certified mobile mechanics can come to your home or office to perform the check engine light diagnostic for.
O2 Sensor Circuit High Voltage (Bank 2, Sensor 2) What Does P0158 Mean?
P0132,p0138,p0152,p0158, o2 sensor circuit high. Discussion starter · #1 · sep 4, 2018. The reason, i suspect, is that the oxygen fuel ratio is incorrectly calculated (because of bad data from sensor 1) which, in turn, causes a rich condition (high voltage) in sensor 2 that is interpreted as a malfunction in sensor 2.
A P0158 Lexus Code Means That The Voltage Was Higher Than Normal On The Signal Circuit.
The pcm detects that the 2/2 oxygen sensor voltage is greater than the maximum acceptable value for a specific amount of time, based on. On rear o2 sensors you may need to raise the idle up until the o2 sensor starts. Oxygen sensor 2 is the downstream oxygen sensor in relationship to the catalytic converter.
Inspect For Holes, Wiring Harness Making Contact With Exhaust, Etc.
P0158 is an obdii code that occurs in many vehicles, including the nissan armada. Continuously with the engine running, no o2 sensor heater dtcs present, 2/2 oxygen sensor heater temperature within a specific range, and battery voltage greater than 10.4 volts. The o2 oxygen sensor circuit high voltage bank 1, sensor 2 is normally located in the catalytic converter, before the muffler, in the.
