on 2002 Toyota Tacoma 2.4L I4 · 4WD

What this code means

Common causes

  • Dirty engine oil/sludge
  • Stuck VVT solenoid
  • Camshaft phaser worn
  • Oil passage blockage
  • Timing chain stretched

Diagnostic steps

  1. Check oil level and condition
  2. Perform oil pressure test
  3. Inspect VVT solenoid screen for debris
  4. Monitor camshaft position with scan tool
  5. Check timing chain condition

Repair notes

Perform oil change if dirty. Replace VVT solenoid. If phaser is worn, replace camshaft phaser assembly.

⚠ STILL BEHIND THE PAYWALL
The 2002 Toyota Tacoma 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.
