Celica Forums General Discussion Exterior Oil Gauge Question

if you are trying to install aftermarket gauges - the gauges should have come with a small device that gets tapped between your lines - and then your new gauge gets hooked to that.

all Oil Pressure gauges that we had sold, comes with this device, thats why Oil Pressure gauges are a bit more expensive than volt and such

Thanks Dude, but I got the mechanical gauge, which has a hollow tube that goes from the block to the gauge. I don't know where in the block it goes. The one that you showed me I think refers to an electric gauge. Maybe I shoulda bought one of those. The other link refers to an Air/fuel gauge, but I got that hooked up noproblem. Thanks for trying though! Maybe I'll toss the damn thing And buy one from Isaac!

not alot. I just don't want to tear all the shit apart again. I hate wiring stuff! Plus I partially pulled the dash to hide everything up. Looks good, but stupid to have a gauge not working!!

oil pressure/temp instal guide
Note: These gauges are made by Autometer and deals specifically with instalation of that particular brand. Gauges of other brand might require different methods to instal properly. However, this guide should still come as a handy reference guide.

Autometers 2-1/16" Ultralite Pro-Comp electrical gauges


Electrical vs Mechanical, what's the difference? It's simple, really. A mechanical type uses a direct acting mechanism to send data to the gauge. In theory, this should provide 100% accuracy. An electrical type transforms the mechanical data to electrical data before sending to the gauge. Improperly calibrated readings of electrical signals increases the chance of false readings. This variable is not present in a mechanical gauge. But, assuming the settings on an electrical gauge is spot on, it should have the accuracy of a mechanical gauge. I wouldn't worry about deciding which is best as they are both proven to be dependable. The tach/speed meter and new drive-by-wire throtle bodies on the Celica are all electrical. If made correctly, it can be very accurate.



OIL PRESSURE SENDER

This is the perfect place to tap in for pressure readings. Even Toyota thinks so. There's another location on the head for the 2ZZ-GE but I personally think this is the best location.

required parts
:1/8" NPT female to 1/8-29 BSPT male adapter
:1/8" NPT T-fitting
:teflon tape
required tools
:crescent wrench or 24mm deep socket

Disconnect the wiring and unscrew the oil pressure switch. Remove any remaining Locktite residue on the thread and block. Screw the 1/8" NPT T-fitting to the 1/8" NPT-1/8-29 BSPT adapter before bolting it on the block. Bolt the adapter to the block. Screw in the stock pressure switch and the oil pressure sender on the T-fitting. Coat all threads with teflon tape.

Note: Be very carefull not to apply excessive weight to the T-fitting when screwing on the oil sender and switch.

Note: It would be wise to isolate the oil pressure sender from the block to avoid possible wear and failure. A high pressure hose and additional fittings are needed.

Thank you very much!! You were a big help

ok!! Got it working!! Thank you daekyu1974, your info was what I needed. I appreciate your help. At idle I got 20lbs or so, steady speed at 60 I got 60lbs, and full throttle it goes 70 to 80 lbs. which all seems good. Thanks again

Thanks dood. BUT I'm not worthy with so many awesome Celicas on this site!

Thanks man

I'm glad you got it working. always a pleasure to help anyone out. I just need to get mine install as soon as I get the meter. I have air/fuel which don't work on 03 GTS. I found that out the hard way.
