P2231: Affordable Fix For Complex Automobile Fault Code
The fault code P2231 indicates a problem with the oxygen sensor circuit on the bank 1 sensor 1.
The causes of this fault code can be a faulty oxygen sensor, damaged wiring, or a failed PCM. The symptoms of this fault code include poor fuel economy, rough idling, and decreased engine performance. The estimated repair time for this fault code is 1.0 hour, and the cost of fixing it can range from $75 to $150 per hour depending on the auto repair shop.
P2231: Oxygen Sensor Signal Circuit Shorted To Heater Circuit
The P2231 fault code indicates a problem with the O2 sensor signal circuit.
Specifically, it means that the signal circuit has been shorted to the heater circuit on Bank 1. This can cause inaccurate voltage signals to be sent to the Engine Control Module (ECM).
The ECM monitors the voltage signal and compares it to factory specifications to determine the state of the circuit.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P2231 fault code. This code is usually caused by a faulty oxygen (O2) sensor in Bank 1 Sensor 1, an open or shorted harness, or a poor electrical connection in the circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to the P2231 fault code, you may have a faulty Oxygen (O2) Sensor Bank 1 Sensor 1, an open or shorted Oxygen (O2) Sensor Bank 1 Sensor 1 harness, or a poor electrical connection in the Oxygen (O2) Sensor Bank 1 Sensor 1 circuit. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Ignoring the P2231 fault code in your automobile, caused by a faulty oxygen sensor or poor electrical connection, can lead to serious consequences. The engine light will remain on, indicating a problem with the engine’s emissions system. This can cause the vehicle to fail an emissions test, reduce fuel efficiency, and potentially damage the catalytic converter. It is important to address the issue promptly by visually inspecting the wiring harness and connectors and checking for damaged components.
Wrap Up
