P106B Possible Causes
- Canister pressure sensor (canister assembly)
- Faulty manifold absolute pressure sensor
- Faulty canister pressure sensor
- Canister pressure sensor harness is open or shorted
- Poor electrical connection in the tank pressure sensor circuit
How to Fix Code P106B?
Start by checking the “Possible Causes” listed above. Visually inspect the corresponding cable harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
Possible Symptoms
Illuminated check engine light (or service engine soon warning light)
P106B Meaning
The code is designed to detect a deviation in the output characteristics of a pressure sensor.
The pressure from the canister pressure sensor and manifold absolute pressure sensor is monitored 55 minutes after the power switch is turned off. If there is a difference in the pressures, the MIL is illuminated (2-trip detection logic).
