360 oil pressure sender, oil thermistor & dashboard gauge ground cables

think I ve a loosen ground connection which causes weird oil temperature and oil pressure readings on the gauges. Oil temperature jumping from 110 to 170 celcius in 10 seconds than eases to 110 again Thermistor,thermostat and oil pressure sender units are new. Only one NTC sensor has not replaced which is placed on the water manifold (180 137 oem number) as there is no problem with water temperature.
Any ideas for the location of ground cables goes to these senders and gauges will be apreciated.

Hakan- Go to ferraridatabase.com and download the wiring diagrams and workshop manuals for the 360. May help you find your problem. The instrument cluster is fairly easy to remove on the 360 and F430, so at least you could get a VOM meter on the instrument panel connectors. Cleaning the connectors with electrical contact cleaner may help, too.

A real obvious thing to check would be the battery ground strap, but you would probably have had other indications if that were the problem.

Thanks Terry. Actually I found 7 ground cables around the dashboard. So instead of removing all the compartment ınsulatıons I wonder to find the correct ground cable that goes to instrument (gauges) directly. Any way thanks agaın for your kind help.

p.s. I found cross referance numbers for the thermostat ,thermistor, NTC sensor. If someone need I can share them.

Hakan- Affirmative, we would love to see them. Cross references can save owners big money.

Sure. I hope someone benefits.

First thermostat link. Instead of €110+tax. It is only 15€ even in Ebay.
You can find the link and matching cars in this link. I choose BEHR (german) one.There you will find the dimensions. if dimensions (spring dimension is very important it should be in 24,5-25,5 mm. range) suits you can use any 79 celcius (strictly max. 79c for Ferrari) thermostat.

Car Part BEHR THERMOT-TRONIK 2.082.79.312 Thermostat, coolant

NTC Sensor. Oem no: 180 137 (you have to buy BOSCH one because operating temperature is -40 to +150)

Sender Unit, oil temperature Ferrari 360 Modena (F131) 360 F1 from Bosch - 0 281 002 170

Also if someone need ignition coil. Each 50€ in this site. Original Bosch.Instead of paying 180€ it is a bargain.

0221504015,Ignition Coil,Ignition Coil - Original Bosch,FERRARI 360 MODENA 3.6,FERRARI 360 MODENA 360 F1- Ignition Car Parts Ltd

Hmm and expansion tank cap. Only 9,65 GBP (16 usd). It is same with peugeot,citoren and fiat commercial vans.

It is not related to ignition,temperature etc. If we re talking about cross reference again you can find complete air flow meter (MAF) sensor or the inner body of the MAF. Again I advise the Bosch.

Well, call me skeptical but BOTH is more a real internal issue than the guages i.e I believe the guages are telling you something. If the issues will continue and something tells me more than not, you'll need to trace the real problem.

IF one or the other then I'd say just a sender problem or lousy oil in the sump.

Well we (my machanics i mean) checked everything. Even we tried another complete instrument panel but the result was same. In the attachment you can see the conflict in water temp. and oil temp. Btw when it is idling also oil pressure warning led is blinking too (which is most probably because of the algortihm between oil temperature and pressure calculaiton in 360s). But i dont think that it is normal for the oil temperature suddenly jumping from 110 to 170 and again from 170 to 110 in 10-15 seconds under normal weather conditions (27 celcius outside) and normal driving style. There is at least 10 liters of oil (shell 10w-60)in the system and and when i check it its thickness and colour is okay.
Okay tomorrow I will check and clean all the ground cable connections and clean them with a contact cleaner spray.
But I am still open to location advices for instrument panel ground cable(s)

Result

Last week I cleaned all ground connections related to temperature senders and the gauges. Result was again same. Than we changed the last NTC sensor which was not replaced. The one on the water manifold! Result is perfect!

So if your oil temperature works fine till it reaches 100-110 celcius (just the mid point) and then begins to jump to 170 celcius (where red warning light is on) with erratic moves than the suspicious sender is 180 137 oem numbered Bosch sensor. It is only 16 .(0 281 002 170 bosch number and it should be bosch because of its working temperature range). It works between -40 to +150 celcius. Btw 430s has 2 of this sender (one instead of crappy thermistor on the gearbox for oil temp. other is on the water manifold for water temp.)

If it reads wrong between 0-80 (oil temperature) celcius than the suspicious one will be the thermistor (it is all with all alfas lancias and fiats). But if it works fine till this level and than it gets mad than the suspicious one the sender on the water manifold.

Hakan- Good information and a lot easier than ripping out the instrument cluster.

Thanks Hankan for sharing the outcome, interesting indeed. Glad that all is perfect now

It look like that on non-USA/CAN F430's, from ass 40465, this very common Bosch NTC sensor is no more used in the cooling system as well as on the Scud/16M.

I have this exact same problem with my 360 Modena it also started jumping from 110 to 170 and then back down again right away & when the red light comes on I freak out . I changed the oil to thicker oil and that did not help, I changed the sensor with another factory sensor and that did not work so I ordered Bosch 0281002170 sensor but the connections were not the same and it was bigger than the factory sensor.

Did you have to modify the wiring .

Any help would be appreciated . My car is a Euro car
