B1269 Code:

OBD-II Diagnostic Body (B) Trouble Code

Possible Cause

The reason of B1269 is system wiring, connectors, or other electrical components are also subject to failure. When this code is set, it is imperative that the transmission be checked prior to further vehicle operation.

Common Symptoms

  1. Engine and transmission ground cables, straps, and wires are sometimes left dangling after repairs are performed
  2. Test the wiring and connectors at the fuel shutoff valve to make sure that voltage and ground readings are near battery voltage
  3. Typical causes of low pump pressure include clogged hydraulic passages, a defective pump, faulty shift solenoids, or a faulty electronic pressure regulator
  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

B1269 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. B1269 OBD2 specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set.

How to turn off B1269 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.
