What is the diagnostic code for 02 sensor circuit high voltage?

What is the diagnostic code for 02 sensor circuit high voltage?

Cost of diagnosing the P0158 code. P0158 is a diagnostic trouble code (DTC) for “02 Sensor Circuit High Voltage (Bank 2, Sensor 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

How to calculate the voltage drop in a circuit?

Answer: First, calculate the total voltage drop allowed in the circuit. This is done by (480 volts x 3%) or 14.4 volts. Then use the three-phase formula for circular mils where K = 21.2 ohms-cmil/ft for aluminum; I = 18 amps; L = 390 ft; and VD= 14.4. So, cmils = 1.732 x 21.2 x 18 x 390/14.4V = 17,900 cmils.

What should be the maximum conductor voltage drop?

Answer:Since Voltage Drop 2 the maximum conductor voltage drop recommended for both the feeder and branch circuit is fi ve percent of the voltage source, the total conductor voltage drop should not exceed (120V x 5%) or no more than 6V less than the source.

How can I check the sensor voltage reading?

Sensor voltage readings should be viewed using Diagnostic Program. NOTE: Always note service codes before clearing codes. Clear stored codes using diagnostic software. Some hard codes, such as code 57, are cleared by turning EMM “OFF” and then “ON” again.

What is the code for sensor reference voltage C?

Codes related to the P0697 include: A code P0697 will be stored when a fault is detected in the sensor reference voltage “C” circuit. The ECM may not be the only control module, including the body control module or fuel injection control module, to detect this particular fault.

What is the diagnostic code for O2 sensor circuit high voltage?

P0138 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit High Voltage (Bank 1, Sensor 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

What causes a cable to fail a high voltage test?

With wires acting as conductors and insulation acting as a barrier, cables can build up high amounts of capacitance. The tester cannot tell the difference between insufficient insulation and unaccounted capacitance. Both causes will result in an overcurrent failure.

How is the voltage of an overvoltage fault calculated?

Corresponding AC voltage at which overvoltage fault occurs can be calculated by dividing the above values by 1.35. These possibilities are discussed in detail below. If the drive is supplying current to a motor with a lot of inertia then the motor could act as a generator feeding voltage back to the drive during periods of deceleration.
