EGR Valve Lift Sensor Circuit Low Voltage

on 2016 Honda Civic 1.5L I4 Turbo · FWD

What this code means

The EGR valve lift sensor signal is too low, so the ECM can't verify EGR valve position. This affects exhaust gas recirculation control.

Symptoms

  • Check engine light on
  • Rough idle
  • Increased emissions

Common causes

  • Faulty EGR lift sensor
  • Wiring short to ground
  • Corroded connector
  • Faulty ECM

Diagnostic steps

  1. Scan and confirm P1488
  2. Inspect EGR sensor wiring and connector
  3. Measure sensor signal voltage
  4. Replace EGR valve/sensor if faulty

⚠ STILL BEHIND THE PAYWALL
The 2016 Honda Civic repair data is incomplete because no one has sponsored it yet. For $99, we generate the full step-by-step procedures, then fact-check them with a second AI pass and your expert review. Your name on every procedure, permanently.
The same data would cost $169/mo from Mitchell1 or $30/year from ALLDATAdiy — and you'd be renting access, not freeing it. Sponsor once, free forever.
