Up and down oil pressure gauge


Low oil level, dirty oil pump pickup screen. Bad sender. Senders are not that expensive to try, but attaching a real pressure gauge into the oil sender fitting would be the last external test you could do.

I have a 1992 Mercury Grand Marquis Ls with a fuel gauge that does not work (gauge may be reversed)??? help please.


The fuel level indicating system is a magnetic type system, which consists of the sending unit located in the fuel tank, an anti-slosh module located on the back of the instrument cluster, and a fuel gauge located in the instrument cluster. The sending unit changes resistance according to the level of fuel in the fuel tank, which varies the current flow through the gauge.The pointer position varies proportionately to the current flow. In this system, the sending unit resistance is low (22 ohms) when the fuel level is low and high( 145 ohms) when the fuel level is high. The pointer of the magnetic gauge remains in position when the ignition is turned to the Off position. On some models, an anti-slosh module is used to dampen out fluctuating fuel signals from the sender. Some vehicles are equipped with a low fuel warning indicator. The anti-slosh module will also actuate the low fuel indicator when the fuel level in the tank reaches 1/16 to 1/8 full.


Do your other gauges/warning indicators work properly with the ignition on? If not, check for power at the fuse panel/fuses.

If they do then partially remove your cluster with connector still installed and check for voltage at cluster connector and gauge. Check continuity of cluster and gauge for ground.

Sometimes the anti-slosh module (if installed) goes bad in the Grand Marquis but not likely.

Sender troubleshooting:
  1. Perform test with resistors as follows:
    1. Disconnect wiring connector at sender unit, then connect resistor between gauge lead and a suitable ground.
    2. Turn ignition switch to On position.
    3. With 145 ohm resistor, the gauge pointer should contact the Full mark.
    4. With 22 ohm resistor, the gauge pointer should contact the Empty mark.
  1. Perform test with fuel sender of known quality as follows:
    1. Turn ignition to Off position.
    2. Disconnect wiring connector from sender and connect it to test sender.
    3. Move float rod away from fuel filter against Full stop position. Wait approximately 30 seconds, then turn ignition switch to On position. The gauge should read on or above the Full mark.
    4. Move float rod toward fuel filter against Empty stop position. Turn ignition switch to Off position. Wait approximately 30 seconds, then turn ignition switch to On position. The gauge should read on or below the Empty mark. If gauge works properly replace sender, which involves dropping fuel tank.

1994 Mercury Grand Marquis temp gauge reads hot


Check sending unit, Ford/Mercury put out a TSB, technical service bulletin : Article No. 95-13-2 07/03/95, on erratic temp sender units.
You troubleshoot as follows :
  1. Turn ignition switch to On or ACC position.
  2. Connect a 10 ohm resistor between gauge lead and ground. The centerline of pointer should fall within the band around the H mark.
  3. Connect a 73 ohm resistor between gauge lead and ground. The centerline of pointer should fall within the band around the C mark.
  4. If gauge tests within calibration, replace sender.
  5. If gauge is out of calibration, replace gauge.

If the check engine light is not on, I doubt there is much you can do.
It sounds like one of the engine temp sensors or one of the other sensors. The engine temp sensor and the intake air temp sensor tell the computer what the outside air temp is and the coolant temp which allows the computer to regulate the amount of fuel going thru the injectors. Generally if one of the sensors has failed the check engine light should be on.
It could be low fuel pressure too.
You may have to have a shop check the sensors with a scanner and the fuel pressure with a gauge.

the sensor is located inside the gas tank, you can access the sender from the front of the tank, just make sure the tank is less than 1/2 full or gas will gush out when u remove the sender retainner ring on the tank to remove the sender, u will need the car on a lift to do this...
