What C0552 means
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 tire 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.
C0552 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.3 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of C0552
- ESC/ASC and ABS warning lamps on, MIL possible on some models
- Stability control, traction control and hill start assist switched off
- Fault returns after load or tire changes
Common causes of C0552
- Most likelyChanged vehicle attitude, e.g. different tire 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
- Less likelyFaulty wheel speed data used as comparison value
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0552 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0552
What does C0552 mean?
C0552 means "Longitudinal Acceleration Sensor Range/Performance". Here the fore-aft acceleration signal arrives but does not match how the car is actually moving. It is a generic code, so it means the same on every make.
Is it safe to drive with C0552?
Drive gently and only to a workshop. With C0552 the car can go into limp mode (reduced power) to protect itself.
Will C0552 fail an emissions test?
C0552 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0552 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2.5 hours of work. This is a job for a workshop.
Will C0552 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
