C0552Longitudinal Acceleration Sensor Range/Performance

  • Generic OBD-II code · Chassis
  • Turns on the check-engine light
  • Can trigger limp mode
  • Needs a drive cycle to confirm a fix
How the car detects it
Here the fore-aft acceleration signal arrives but does not match how the car is actually moving. Mitsubishi's 2023 Outlander PHEV brake controller reports its built-in decel G sensor fault C1071-64 as C0552; the check needs a healthy supply and takes up to 2 s, and a second faulty drive turns on the ASC and ABS warnings as well as the check-engine lamp. ASC, traction control, brake LSD, brake assist, brake force distribution and hill start assist are suspended. Mitsubishi lists altered vehicle attitude (different tyre sizes front and rear, overload) and a wrongly angled ABS unit among the causes. Patents describe the test: Sumitomo (now Advics) relates the sensor value to the derivative of the fastest wheel speed and, after repeated misfits, has ABS use wheel data only; Bosch adds offset and range checks on straight roads.
What you may notice

Likely causes
  • LikelyChanged vehicle attitude, e.g. different tyre sizes front and rear or overload
  • PossibleABS/ESC unit or sensor mounted at the wrong angle or loose
  • PossibleSensor offset drifted or internal sensor defect
  • RareFaulty wheel speed data used as comparison value
