Details of the Toyota p2bab OBD Code
Code P2BAB in a Toyota indicates a problem with the exhaust gas recirculation (EGR) cooler control circuit.
Code P2BAB for Toyota vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit Range/Performance.
This code is triggered by the Engine Control Module (ECM) when it detects that the signal from the EGR cooler bypass control circuit is outside the expected range or not performing within specified parameters.
The EGR system is responsible for recirculating a portion of the engine’s exhaust gas back into the intake manifold to reduce combustion temperatures and emissions.
In this case, the issue lies specifically with the control circuit related to the EGR cooler bypass function.
