C0950Tire Pressure Monitoring Sensor Front Left
- Generic OBD-II code · Chassis
- Needs a drive cycle to confirm a fix
- How the car detects it
- No public source links C0950 to a carmaker. The same content, the left front tire sensor, is documented under other numbers: GM and Saab use C0750, whose 2011 Saab 9-5 subcodes split a weak cell (03), too few telegrams (29) and an internal defect (39); Mitsubishi's 2022 index carries C1731 for the front left sensor and C1741 when its data stay away. GM bulletin PIC5650M lists C0750 among the codes that radio interference from aftermarket devices can cause, so the environment belongs in the diagnosis. As a catch-all for the front left unit the code covers a sensor that falls silent, reports nonsense or is not learned. Air pressure itself is not the issue; the indicator shows a system fault and that wheel loses its value.
