Location of coolant temp sensor on a 94 olds 88 royale

Here you go copy and past then click on the first picture. It's number 5. https://www.google.com/search?client=ms-android-americamovil-us&ei=59KZWYn7DcPymQG4yoOIDw&q=1987+oldsmobile+delta+88+royale+brougham+map+sensor+location&oq=1987+oldsmobile+delta+88+royale+brougham+map+sensor+location&gs_l=mobile-gws-serp.3...4920.20339.0.21667.21.21.0.0.0.0.406.5585.0j1j16j2j1.20.0....0...1.1j4.64.mobile-gws-serp..1.17.4932...0j0i22i30k1j33i22i29i30k1j33i160k1j33i21k1.dB-spKCclH4

It doesn't show an 'engine temperature sensor' for that year, make and model
What you do have is a Coolant Temperature Sensor (there are actually one of each on other makes and models - an engine temperature sensor and a coolant {radiator fluid} sensor). Just doesn't appear to be a separate engine temp sensor for the 94 2.5. The coolant temperature sensor is the sensor that will make your temp gauge in the car move. It's location is - Under hood, center, front engine area, near distributor, mounted in driver side of cylinder head. I've attached a pic of the sensor for you.

You also have an intake air temperature sensor and an ambient air temperature sensor that tells the computer the temp in the vehicle's cabin. I can shoot you that info if your question wasn't answered above.



Good Luck & All The Best, Justin Lee

Crank position sensor...i have same car and that happened to me

These cars had a very common problem with a sensor that is mounted behind the crankshaft pulley. It is difficult for the home mechanic to change as special tools are required, but not that bad at a shop. About 200 bucks. It is called the "crankshaft position sensor". If you have this replaced, I'm certain your intermittent shut down will be fixed.

For 1994 Oldsmobile 88 3.8L SFI OHV 6cyl the Engine Control Computer is located front seating area, passenger side, under dash, mounted above kick panel.

Hope helps (remember to rate this).

I would check the crankshaft and camshaft sensors. I don't think the connections are wrong, they really only go on 1 way.

Here's a link to the serptentine diagram for our '94 Olds 88 Royale...

Poss crank sensor or ignition mod.
Dont remember which terms to cross with the paper clip... been awhile!

Depending on where you are located... alot of shops do a cheap test or even free to throw the comp on!
