P01FETurbocharger Outlet Pressure Sensor B Intermittent/Erratic
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- Turbocharger outlet pressure sensor B is a second pressure sensor at a compressor outlet – for example one per turbo on twin-turbo engines or a second measuring point; sensor A has the codes P00F8–P00FC. It is a separate family from the boost pressure sensor: GM and Ford report the pressure ahead of the throttle under the boost sensor codes P0236–P0238. No manufacturer using the sensor B codes was found; FCA documents sensor A and a second outlet sensor. P01FE counts brief spikes or dropouts that are too short for the low or high code. Ford's equivalent boost sensor check sets after 10 such events in one drive cycle. The usual cause is a loose or corroded contact or a wire broken by vibration and heat.
