Question about 1996 Ford Thunderbird LX

1 Answer

Temp guage read hot, volt guage reads low, and oil pressure guage tops out. Could this be a bad ground?

I have a 1996 ford t-bird. The temp gauge will show hot, while the volt guage will show real low, and the oil pressure guage will be all the way topped out. Doesn't seem hot, never boiled over, never needed water/coolant. Could it be a bad ground?

    Hey thank you so much for your help. I wondered also about the head gasket. What brought you to that theory if i could pick your brain. I am not losing coolant. I guess i always thought you had to be losing coolant to have a blown head gasket. Also there is no water in the oil, or no oil in the coolant.

Possibly, i would check the sending unit and of course the wires that connect to the temp prob. They often become worn or even short out on other wires. I suspect that the gage is telling the truth and you have a blown head gasket. Check the oil for water. Check the water level and see if you are losing water. good luck

OHMS Resistance for temp gauge


The OHM's are different from manufacturers. Usually the work or don't. I just test the leads and heat up the sensor with a lighter. If the resistance changes, it is good. If it doesn't read or doesn't change, it is bad. Wires usually break right behind the plug. Check for continuity at the lead and about two inches back on the wire.

How to you check to see if the oil pressure guage is bad or if there's a pressure problem itself?


Connect test leads to the guage and apply 12 volts, if the guage activates upward this works, if it's the oil preaaure in regards to the oil pump, you need to hook up a oil pressure guage.

79 c10 - guages all read low except gas guage which reasd high. Truck runs fine. Lights work, even the dash lights work good.


It sounds like you might have a poor ground connection somewhere. You can test each individual gauge for full travel by grounding the wire the goes the each gauges individual sender. In other words to check the temp gauge, ground the wire that goes to the temp sender. The temp sender is in the left cylinder head between the #1 and #2 spark plug ( looks like a brass pipe plug with a single wire coming from it) if you ground the wire with the key on (engine off) the gauge should go to the end of the scale (hot) with the wire off it should go to full cold. You can do this with the gas gauge too but not the amp gauge or volt meter. If the volt gauge is reading low (if it has one) and you know that battery voltage is good (don't guess, measure with a multi-meter) there has to be a poor connection somewhere.

My oil pressure guage is at the upper safe limit when at idle and tops out when I am moving. Is this a guage issue or a mechanical issue requiring immediate repair?


It could be a bad gauge or a check valve could be stuck or blocked causing your oil pressure to be too high. Have your oil pressure checked at a shop.

Gas guages messed up


volt meter, fuel gauge, oil pressure and coolant temp all share the same power and ground

the circuit you want to check is the yellow and white wire from the dash to the dual switch

1990 honda accord temp gauge above hot limit.


Hi there,

Firstly - DO NOT run engine, when guage reads hot, as this will cause costly damage to head gasket & alloy engine head.

The fact that guage takes 1min to read HOT, would confirm the guage IS working properly.

So, other components which are likely to cause hot readings (in this order) are:

- lack of coolant (or leakage somewhere): is there sufficient green coolant at the correct level? Top up mixture to correct level. Repair any leaks.

- collapsed radiator hose: when engine is cold, start engine, then quickly watch both upper & lower radiator hoses to see if either begins to flex inwards (collapse). Replace if either hose is collapsed.

- bad/incorrect thermostat rating : when replacing thermostats, you must ensure it is of the SAME temp rating (they all differ).

- Incorrect Temp sensor rating: the ratings of this sensor must be within manufacturer's spec's.

- bad waterpump: the engine relies on the waterpump to distribute the coolant throughout the entire system. If waterpump is faulty, coolant will not flow quick enough, causing overheating.

If you still believe all of the above components are OK, then have your cooling system "pressure tested". This test should be done, before looking further at other electrical components.

Cheers,
