i recently installed an autometer oil pressure gauge (mechanical). my question is will there be any effect on the computer by not having the stock gauge/wiring not hooked up? i know with water temp it needs to be hooked up but not sure with oil pressure. thanks

My1stGT

anyone?

I think oil pressure only goes to the gauge. I teed mine off to run both sensors just in case. You can get the plumbing from your local hardware store.

beat me to but its not that bad

a_penquin

He still hasnt replied to my two questions 1: where is he mounting it and 2: dose he have a oil cooler (factory or aftermarket). I was going to give him routing advice, tap in location, light wiring and firewall penetrations.

i mounted mine on pillar, along with temp gauge. i tapped into defrost lights so i can also dim them. where did you tap into and wire from?

a_penquin

Im running a 3 pillar with electric gauges but its all the same in the end. I tapped directly to the dimmer switch. I have a pics of the gauges and plumbing below.

a_penguin, thanks for all ur help BTW.

My1stGT, has your car triggered any CEL light of any kind?

From what I can find, you might trigger one of these three ODBII errors:

P0196 - Engine Oil Temperature (EOT) Sensor Circuit Range/Performance
P0197 - Engine Oil Temperature (EOT) Sensor Circuit Low Input
P0198 - Engine Oil Temperature (EOT) Sensor Circuit High Input


Those three have to do with the EOT calculating your oil temp. I'm assuming that it will throw an error after it realizes that it cant get a temperature.

*edit*
This one might also be possible:
P0298 - Engine Oil Over Temperature Condition (because the EOT sensor doesn't exist). This one will retard your motor so It cant run at high speeds. (because it thinks your engine/oil is too hot)
