P1282 Code:

OBD-II Diagnostic Powertrain (P) Trouble Code

Possible Cause

The most common causes of this P1282 code being stored are due to a defective input speed sensor or output speed sensor. Other common causes include shorted, open, corroded, or damaged wiring circuits or connectors.

Common Symptoms

  1. Individual control module failure is rare but possible
  2. Test the wiring and connectors at the fuel shutoff valve to make sure that voltage and ground readings are near battery voltage
  3. A scanner (or code reader) and a digital volt/ohmmeter will be required to successfully diagnose this code. Virtually every vehicle (with an automatic transmission) produced since the mid-eighties is equipped with some type of computer controlled automatic transmission system
  4. The sensor is of the electro magnetic design and uses a reluctor ring (or a specialized set of splines) on the input shaft as reference points

P1282 Troubleshooting

If there is a clicking noise when you attempt to start the engine and the engine does not crank, it typically means there is something wrong with the battery, such as a low or discharged battery or corroded or loose battery cables. If the engine cranks when you attempt to start the car, but fails to turn over, this may mean there is a problem with the fuel or ignition. Other common reasons an engine may fail to start include a failure of the starter motor relay, a clogged fuel filter, a defective fuel pump or an ignition switch failure. P1282 OBD2 may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.

How to turn off P1282 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.
