What O2 sensor is bank 2 sensor 2?
The O2 sensor 2 is the downstream O2 sensor and it measures the amount of oxygen in the exhaust gases leaving the catalytic converter (cat).
What is a HO2S sensor?
The Oxygen(O2) Sensor is installed in the exhaust system to determine the amount of oxygen left in the exhaust stream after combustion. This is used by the ECU to determine if more or less fuel (longer or shorter injector duration) is need to achieve optimum air/fuel ratios.
What causes code P0135?
Code P0135 occurs when the powertrain control module tests the upstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit.
How do you fix P0051?
What repairs can fix the P0051 code?
- Replacing bank 2 sensor 1.
- Fixing the connection issues and reattaching the connectors.
- Repairing any open or shorted wiring.
- Replacing the heater circuit fuse.
- Replacing the ECM.
