P0954Auto Shift Manual Control Circuit Intermittent
- Generic OBD-II code · Powertrain
- How the car detects it
- The manual up/down request signal drops out or flickers for short moments, so a single tap may arrive twice, late or not at all. Unlike P0952 and P0953 the voltage is not stuck outside its window; it jumps between states without a matching lever movement. Typical triggers are loose pins in the shifter connector, worn contacts or a harness that flexes with the lever. A Chrysler patent shows how simple contact switches in the gate signal each request, a Volkswagen patent how Hall tip sensors and their lines are checked. No manufacturer documents this exact code publicly; CARB requires circuit checks. P0950 is the general fault. The driver notices missed or doubled manual shifts.
