NOx & O2 Sensor Solutions
Precise DTC suppression for failing sensors
From£180
What It Is
NOx and oxygen sensors live in the hottest, harshest part of your exhaust — and they fail often. Replacements routinely cost hundreds of pounds each, sometimes requiring multiple sensors before the fault clears.
Where appropriate, we apply precise diagnostic trouble code (DTC) suppression within the ECU so a failing sensor stops plaguing the vehicle — targeted suppression of specific codes, never blanket deletion.
Signs You Need This
- Recurring NOx sensor fault codes
- Multiple sensor replacements without lasting fix
- Emissions warnings with no drivability cause
- Sensor cost quotes exceeding the vehicle value
What's Included
- Live-data diagnosis to confirm sensor failure
- Targeted DTC suppression for affected circuits
- Verification that no other faults are masked
- Original file backed up
