How does a fault code arise in the Sensors group?
This heading collects codes that belong directly to sensor circuits rather than to a particular subsystem: signal supply, ground, wiring integrity and whether the signal sits in a plausible range.
The key distinction is between “circuit” and “performance”. A circuit code — high input, low input, open circuit — reports an electrical certainty and is usually resolved at the wiring, the connector or the sensor. A performance or range code says the signal is electrically valid but physically wrong. Because the sensor appears to be “working”, replacing parts is the most common mistake with these codes.
Connector corrosion and poor chassis grounds cause codes in this group more often than the sensors themselves. Replacing a sensor without measuring usually ends with the same code returning a few days later.
Fault codes in this group
The database holds 12 codes in this group. Each code has its own page with the meaning, possible causes and diagnostic steps:
Read fault codes on your own vehicle
With an ELM327-based BLE OBD2 adapter, CarCoding reads confirmed, pending and permanent fault codes separately, pulls the freeze frame and explains every code in plain language. Clearing codes is done from the app as well. The app is free to download.
Some advanced features require an in-app purchase.
Data source: the CarCoding fault code database. Code definitions follow the SAE J2012 standard; manufacturers may use different wording for their own codes. Everything on this page is generated from the code-specific database records.
