Error P06B5 on FAW все модели

Symptoms

• Check Engine Light Is On
• Inflated readings from group B sensors or their complete absence
• Many related sensor error codes
• Engine emergency mode
• Possible physical damage to sensors due to contact with high voltage

Causes

• Break in the power supply wire for sensors of group B (all sensors have lost load)
• Shorting the power line to a circuit with a higher voltage
• Malfunction of the internal sensor power supply stabilizer in the ECU
• Damage to the harness with contact with the 12V body power wires
• Non-original sensor with non-standard circuitry

How to Fix

1. Read codes, identify group B sensors according to the car diagram
2. Measure the voltage on the Group B power line (expected to be higher than normal)
3. Disconnect all sensors of group B and re-measure the voltage
4. If the voltage has returned to normal, connect the sensors one by one and identify the faulty one.
5. If the voltage remains high, look for contact with an external circuit or check the ECU
6. Fix the malfunction, reset the codes, check the result
