Tachometer Check

WARNING: This page is about a different car, the 2003 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: For tachometer check, use an external high quality inductive tachometer.

  1. Attach an external high quality tachometer to the engine speed detection connector on the harness side (such as with a paper clip).
  2. Compare the readings of the vehicle tachometer and the external tachometer at every engine speed, and check if the variations are within the standard values.

    Standard values: 

    • 700 r/min:  +/- 100 r/min 
    • 3,000 r/min:  +/- 150 r/min 
    • 5,000 r/min:  +/- 250 r/min 
    • 6,000 r/min:  +/- 300 r/min
