Turbo/Supercharger Boost Pressure Sensor Circuit Intermittent

on 2017 Jeep Wrangler 3.6L V6 · 4WD

What this code means

The boost pressure sensor signal is intermittent, causing erratic boost control. The PCM detects signal dropouts or sudden voltage changes.

Symptoms

  • Check Engine Light intermittent
  • Fluctuating boost gauge
  • Inconsistent power delivery
  • Occasional limp mode
  • Surging under load

Common causes

  • Loose boost pressure sensor connector
  • Damaged sensor wiring
  • Faulty boost pressure sensor
  • Vibration-related intermittent contact
  • Corroded sensor pins

Diagnostic steps

  1. Monitor boost pressure PID for signal dropouts
  2. Wiggle test on sensor connector while monitoring data
  3. Inspect sensor connector pins for corrosion
  4. Check wiring harness routing near heat sources
  5. Swap sensor with known good unit if available

Repair notes

Replace boost pressure sensor or repair intermittent wiring connection.
