The manual does not say how to change from centigrade to farenheit?

(centigrade x 1.8) + 32 = farenheit

Example 12 degrees C = 12 x 1.8 +32 = 53.6 F

Engine temp sensor bypass or test

WHAT SIZE ENGINE???? ? 4L 2.5L????

ive seen this post many times now.and can not figure it out.
double posted.
what are you trying to do, say that first. or just ask a question
first off,what does bypass mean???? <<very confusing to me...????
This is THE ECT, the ENGINE. Coolant Temperature" sensor.

what do you wish to do with this very critical EFI sensor.???????
just test it.>
Ill guess, you have not read the FSM , as it covers that 2 ways.
the ECT can be tested 3 ways.
ill show 2
1: on car and off car.
1: on car. (is more easy. if strong back)
DMM set to RESISTANCE , aka. ohms. ohmega symbol
the DMM meter is $20 at walfart.
cold car, say at about 50f.
you unplug the ECT connector (2 pin conn)
cold engine it might read, 5000 ohm, this is good,
get engine fully hot. i use a IR pyro gun, it hit 180F or more.
and kill engine.
pull back off the ECT sensor. conn.
and it reads (2 pins 2 meter leads) about 300 ohms.
is this what you want.

first google hit on sensor , but FSM shows truth....
1st hit shows....... its a NTC thermistor with these rules.
212 farenheit 185 ohms
160 farenheit 450 ohms
100 farenheit 1600 ohms
70 farenheit 3400 ohms
40 farenheit 7500 ohms
20 farenheit 13,500 ohms
0 farenheit 25,000 ohms
-40 farenheit 100,700 ohms

the FSM is here
the 93 will be close.

click fuse system there.
click on pdf page number. 46/66 BINGO ECT TESTS>

off car tests are easy, in a pan of room temp water then hot the in
ice water.
i do 3 tests. 32F(ice) 79F (room) and 200F (near boiling)
super easy test. ask how. if any step seems confusing.

My a/c control settings went from farenheit to celsius. How do I change it back?

The C/F format for the outside temp display (on rearview mirror) can be changed by depressing the switch for an extended period (Instructions are in the owners manual, page 2-54). The inside temp C/F format (on the automatic climate control) is changed via the "English/Metric" selection on the DIC.
