C0083Tire Pressure Monitor Malfunction Indicator
- Generic OBD-II code · Chassis
- How the car detects it
- Covers the tyre-pressure-monitor indicator (TPMS lamp) as driven or monitored by the responsible module. Regulations distinguish a steady low-pressure warning from a flashing TPMS-malfunction indication; this code concerns the indicator path, set when the TPMS lamp circuit is open or shorted, the lamp does not respond, or the commanded and observed states disagree. A system that cannot monitor pressure, for example an indirect system that has lost its wheel-speed reference or a direct system missing sensor data, requests the malfunction indication, and a fault in that path sets this code. Indirect-TPMS patents describe deriving pressure from ABS wheel-speed signals, so a loss of that data can drive both a TPMS fault and this indicator code. No code-specific public bulletin was confirmed; the entry follows the SAE J2012 generic definition.
