C0824 Code:

OBD-II Diagnostic Chassis (C) Trouble Code

Possible Cause

Common causes of C0824 is include shorted, open, corroded, or damaged wiring circuits or connectors, faulty shift solenoid/s, defective engine drivability sensors (especially the engine temperature sensor), dirty or contaminated transmission fluid that restricts flow, defective valve body, a faulty PCM. PCM failure is rare.

Common Symptoms

  1. If all of the exhaust gas temperature/pressure (or heated oxygen) sensor circuitry appears to be in proper working order, then proceed with the diagnostic procedure
  2. Unlike other diagnostic codes, this type of code can sometimes be best left to a professional simply because of the bulk of circuitry involved
  3. The PCM will read the sensor resistance and pass it
  4. Typical causes of low pump pressure include clogged hydraulic passages, a defective pump, faulty shift solenoids, or a faulty electronic pressure regulator

C0824 Troubleshooting

When you put your foot down on the brakes you expect your car to quietly slow down and come to a stop. The power your foot applies on the brake pedal is assisted by hydraulic pressure. Your foot's force engages a piston and caliper with brake pads attached (bonded abrasive and heat resistance metal or ceramic) to put pressure on the rotor. C0824 OBD2 reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.

How to turn off C0824 check engine light ?

There are two ways to turn off the check engine light:

A repair technician can do so once repairs have been made.
The OBD II can automatically turn it off when it fails to detect the problem after several diagnostic cycles.
