P2237: Oxygen Sensor Positive Current Control Circuit/Open – Explained
The P2237 code refers to a fault in the oxygen sensor positive current control circuit.
This circuit is responsible for regulating the amount of current flowing through the oxygen sensor.
The fault occurs in Bank 1 Sensor 1, which is located in the exhaust manifold.
The oxygen sensor measures the amount of oxygen in the exhaust gas compared to the outside air.
It generates a voltage signal that is sent to the Engine Control Module (ECM).
The ECM uses this signal to adjust the injection pulse duration to achieve the ideal air-fuel ratio. The P2237 code indicates that there is an open circuit in the positive current control circuit of the oxygen sensor. This can cause the ECM to receive an incorrect signal from the sensor, leading to poor engine performance and increased emissions.
It is important to have this issue diagnosed and repaired as soon as possible to prevent further damage to the vehicle.
FAQ
