P2240: Affordable Fix For Complex Automobile Fault Code
The automobile fault code P2240 indicates an issue with the oxygen sensor circuit in Bank 2 Sensor 1. The estimated repair time for this fault code is 1.0 hour.
The cost of fixing this issue varies between $75 and $150 per hour, depending on the auto repair shop. Other factors that may influence the cost include the location of the shop, the type of vehicle, and the severity of the issue. It is important to address this fault code promptly to avoid further damage to the vehicle and ensure optimal performance.
P2240: Oxygen Sensor Signal Circuit – Range/Performance
The P2240 code indicates a problem with the positive current control circuit of the O2 sensor in bank 2, sensor 1. This sensor is located in the exhaust manifold and measures the amount of oxygen in the exhaust gas. The O2 sensor 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.
If the positive current control circuit is open, the ECM will not receive a signal from the O2 sensor. This can cause the engine to run rich or lean, resulting in poor fuel economy and increased emissions.
It is important to have this issue diagnosed and repaired as soon as possible to prevent further damage to the engine.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P2240 fault code. This code is caused by a faulty front heated oxygen sensor bank 2, an open or shorted harness, or a poor electrical connection in the front heated oxygen sensor bank 2 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.
If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Front Heated Oxygen Sensor Bank 2, you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the Front Heated Oxygen Sensor Bank 2 harness is open or shorted, or if there is a poor electrical connection in the circuit.
Ignoring the P2240 fault code in an automobile, which indicates a faulty front heated oxygen sensor bank 2, can lead to decreased fuel efficiency and increased emissions. The engine light will remain on, and the vehicle may fail an emissions test. It is important to visually inspect the related wiring harness and connectors and check for damaged components to fix the issue.
Wrap Up
If your engine light is on and the code is P2240, it may be due to a faulty front heated oxygen sensor bank 2, an open or shorted harness, or a poor electrical connection.
