Category
Powertrain
Severity
🔴 HighSymptoms
- 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
- Read codes, identify group B sensors according to the car diagram
- Measure the voltage on the Group B power line (expected to be higher than normal)
- Disconnect all sensors of group B and re-measure the voltage
- If the voltage has returned to normal, connect the sensors one by one and identify the faulty one.
- If the voltage remains high, look for contact with an external circuit or check the ECU
- Fix the malfunction, reset the codes, check the result
FAQ
Нужно ли срочно глушить двигатель при P06B5?
Если подозревается замыкание на цепь 12В — да, следует немедленно заглушить двигатель, чтобы не допустить повреждения дорогостоящих датчиков. При обрыве срочности меньше, но диагностика необходима.
Может ли P06B5 возникнуть после ремонта проводки?
Да, если при ремонте был случайно соединён провод питания датчиков с проводом кузова или другой питающей цепью.
