Gauge Always Indicates High Pressure (Van)
- Disconnect wire at sending unit. Turn ignition on. Connect fused jumper wire from sending unit Tan wire to ground. If gauge indicates low pressure, replace oil pressure sending unit. If fuel gauge indicates high pressure, go to next step.
- Remove jumper wire. Connect self-powered test light between instrument cluster connector terminal B8 (Tan wire) and sending unit Tan wire. If test light comes on, replace instrument cluster. If test light does not come on, repair open circuit in Tan wire.
