P0CADHybrid/EV Battery Temperature Sensor N Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0CAD stands for an electrical problem with battery temperature sensor N that the controller cannot assign to a specific failure type. Public manufacturer documentation for this exact code does not exist. GM's 2011 hybrid rationality list places N fourteenth among sixteen sensors, while its tables from 2012 onward cover N only with the specific codes P0CAE to P0CB1. On the plug-in Outlander, Mitsubishi equates N with module sensor [13] and likewise separates only rationality, short and open. CARB section (e)(15.3.1) is the basis for permanent monitoring of such input circuits. A pack controller without this reading has to plan conservatively for that section. Because the sensor lives inside the traction battery, checks are made only after the high-voltage system has been isolated.
- What you may notice
- Hybrid or EV system message
- Battery power reduced until repaired
- Likely causes
- LikelyConnector or wire fault between sensor N and the monitoring board
- PossibleThermistor N defective
- RareFaulty input channel of the cell monitoring board
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
