Hello, crank position sensor located at the 2 o`clock position hidden behind timing cover and crank shaft pulley. If you look closely in well lit area or use a flashlight you can follow the (CCPS) harness down the right hand side of timing cover to where it goes into lower timing cover on lower right hand side of crank shaft pulley. It can be replaced with out removing timing belt. Please note if the 60,000 miles heavy service interval for timing belt is needed and water pump condition should be observed when repairing the crank position sensor.

Follow the link for instructions, and yes 2003 is the same.

Check the cam & crank position sensor. Then look at the Throttle position sensor. Finally check for intake leaks.
