C0952 Tire Pressure Monitoring Sensor Rear Left

A manufacturer using C0952 is not on record; the number is absent from all lists and bulletins searched. What it names, the left rear tire sensor, carries other codes elsewhere: C0760 at GM and Saab, C1734 and C1744 in Mitsubishi's 2022 index, and on a 2008 Honda Accord the codes 37 for a low sensor battery and 38 for a sensor that stopped transmitting at the left rear. Relearning follows a fixed sequence of corners; Honda starts with the front left wheel, moves on to the rear left one, then the rear right, and finishes at the front right, and Saab's autolearn tells the axles apart by signal strength. A left rear fault therefore often follows a wheel rotation or a missed relearn step. The left rear pressure is no longer monitored.

Likely causes

Wheels rotated without relearning sensor positions
Cell of the left rear sensor exhausted
Sensor damaged or missing after tire work

Symptoms

  • No reading for the left rear tire
  • TPMS warning after a tire rotation
