C161E code in owner complaints

What the code means

This is a manufacturer-specific code: the meaning depends on the make and sometimes on the year.

How to read C161E: the letter C means chassis (brakes, ABS, steering, suspension); the second digit 1 marks a manufacturer code whose meaning is set by the make; the last three characters 61E identify the specific fault.

Codes for engine, transmission, transfer case and hybrid system modules. When valuing an auction car the key question is whether the fault is crash related (cut wiring, damaged radiator) or a known defect of the model.

• Acd C161E was read in the ecu. It's ayc acd pump failure. I didn't drive hard. I drove normally which I usually do. And 4wd service required comes on. I searched a lot about the issue. Mitsubishi should have a recall about this its a common problem for evo I read.

• I arrived home from my trip and was at the dealership at 36,200 miles. Their scanner indicated a C161E code which indicates an acd pump actuator lock. The dealership stated this can happen under aggressive driving conditions and was normal.
