Gauge Always Indicates Low Pressure (Motorhome)

  1. Disconnect engine oil pressure gauge sensor. Turn ignition on. If oil pressure remains low, go to next step. If oil pressure moves toward high, replace engine oil pressure gauge.
  2. Backprobe with a test light between instrument cluster connector terminal No. 21 (Tan wire) and voltage. If test light does not come on, go to next step. If test light comes on, repair short to ground in Tan wire.
  3. Backprobe with a test light between instrument cluster connector terminal No. 20 (Black wire) and voltage. If test light does not come on, repair open circuit in Black wire.
