Checklist Preview

  • EFI: scan for fault codes before clearing
  • EFI: capture freeze-frame and live data
  • EFI: verify fuel pressure key-on, idle and load
  • EFI: check injector pulse with noid light or scope
  • EFI: inspect TPS sweep for dropouts
  • EFI: compare MAP/MAF readings against engine state
  • EFI: compare coolant and intake temperature cold
  • EFI: check sensor grounds and 5V reference
  • EFI: inspect intake leaks after throttle body
  • EFI: record corrected live-data values

How To Use It

Use this checklist before replacing parts. Work from the top down, record the result of each step, and only move to repair decisions when the failed test is clear.

The downloadable PDF includes checkboxes, notes space, final verification and technician sign-off fields for workshop records.

SEO and Research Notes

This original Motomech worksheet is built from common workshop inspection logic: verify the complaint, inspect safety-critical systems first, measure before replacing parts, document the failed test, and finish with a repeatable road-test or service verification.
