Installation (2.5 & 4.0L)

  1. To install, reverse removal procedure. Use only proper mounting bolt. Any other replacement bolt will cause improper sensor alignment.
  2. On some Grand Cherokee and Wrangler models with 4.0L engine and automatic transmission, crankshaft position sensor is secured by a single bolt. On models so equipped, ensure paper self-adhesive spacer on end of sensor is replaced if old sensor is being reused. Paper spacer is used to set proper depth. Once engine is started, paper spacer wears away.
