Nitrogen Oxides (NOx) Sensor Module: Removal
WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Do not use silicone based sprays or lubricants on any components installed onto or around the diesel exhaust system or intake air distribution and filtering system. Silicone reacts with the Nitrogen Oxides (NOx) sensor and may cause permanent damage to the NOx sensor.
- Turn the ignition switch to the OFF position.
- Disconnect the Nitrogen Oxides (NOx) sensor electrical connector and the Nitrogen Oxides (NOx) sensor module electrical connector.
- Remove the 2 bolts and the NOx sensor module.
NOTE:
Make sure the ignition switch is in the OFF position prior to working on the electronic engine controls or the vehicle may be damaged.
NOTE:
Any melting of plastic connectors indicates overheating of the Diesel Particulate Filter (DPF). Address any DPF concerns before installing a new sensor.
