Im trying to decipher the wiring diagram in the bentley service manual. in this 1964 Mustang Wiring Diagrams pictures the battery, starter relay, temperature sending unit, courtesy light switch, fuel gauge, transmission selector dual light, temperature gauge, oil pressure sending unit, generator regulator, constant voltage unit, oil pressure. The ground is typically through the. When this sensor goes bad, it will start to give inaccurate readings. The sending unit reading should be in the 30 to 55 ohm range, depending on the operating temperature, speed and oil viscosity. 5 TD specialists, a brand new HD GM transfer pump/oil pressure switch/sending unit, aka: OPS Switch. The best, and cleanest, way. Fuel gauge has a built-in voltage limiter to keep voltage supply to gauges at 7 volts. P0523 means the Oil pressure voltage to high. Also worth mentioning, a warning message on the dash stated low oil, turn engine off. To work properly, the MG fuel level and coolant temperature gauges need to be used with an external Voltage Stabilizer. For the fuel gauge I used the 5v output from the arduino and a simple voltage divider circuit to determine the resistance of the sending unit. Starts in oil pan. Write a review $ 51. It is an oil pressure switch that is supposed to close below 4 psi to activate a dash warning light in some speedometer clusters. It indicates if the engine's oil pressure has fallen below a critical level of ~ 3-10 psi, depending on the engine. P0545 : A/C Clutch. sure it is the correct OHM and VOLTAGE. The sending unit is the "ground" portion of the circuit. Checked voltage on grey wire coming out of the pump relay and get 12 volts there for a couple of seconds, which I guess is the priming voltage. Shipping: inside cont 9l 24v Cummins turbo diesel. Nighttime dimmer. 7lt and 152,000 mi it started giving me signs with falling rocker arms twice.
