My '92 Loyale single point fuel injected engine has been a dream fast start up since I bought it new. No matter how cold here in NJ over the years, it started quick, and I could immediatly drive it. I didnt ave to let it idle to warm up to drive. I could drive it right off the get go even when temps dipped into the low teens.

Last week , all of a sudden, it acts as if it has a old carberator with no choke. I have to pump the heck out of it to keep it running for a min or so. Then pump it to accelerate. Once the motor warms up it drives just fine. I believe my choke system has failed. Just waht I need now with temps in the 20's tomarrow:confused: ALL the fuses are good. It being throttle body fuel injected, I'm at a slight loss as to identifing compnentes on the throttle body.

IF my fuses (under the dash) are all good, where do I begin to get my choke working again????

start by finding the

FI CTS (Fuel Injection Coolant Thermosensor)

 

It is located on the upper rad hose connection

on the engine.

 

NOTE: there are two coolant sensors located there

The one you want has wires running into the sensor.

The wrong one has a just spade connecter.

 

You can take the FI CTS connector (barrel shapped)

apart and clean the contacts

 

but the sensor is probably bad.

 

IF you have a mulitmeter you can test it.

is it the green connector in the picture (hope it posted) or what it's connected to at the perceived themostat housing. It has 2 wires to it. The other is a single wire going to another area close by

Can I remove the sensor without loosing too much antifreeze?

The picture is poor due to limits here on size.

That may be it.

Pictures here should be about 700 pixels wide.

Reduce them and they will fix,

 

Please see this link, I hope it helps

You can test it without removing it

 

You will loose some coolant, make sure you top it off.

if engine is warm/hot, what should multi meter show? ohm value or on/off. i've had car running and now is too hot to remove sensor for testing. but if i wait hehe it'l cool quick realy windy cold here:mad:

Please use the chart I provided

 

It is a varriable resistance and not an on/off switch

Just got a 0.6 x 10k or 6,000 ohms at 5pm. I assume if let sitting till , say 5:30 or 6pm, ohms should go up. Contacts in that green connector look real clean should this check out ok,??????

Are you having trouble

a) seeing the chart linked to?

understanding what it means?

Sorry SKIP, I'm in hyper mode with the cold / dark to get this figured out. I asked the questions before I noticed everything on the wonderful chart you posted, my mistake Bruce

Snow worries, mate

 

With the reading you saw and the engine temp

somewhat warm,

I would have to say

the sensor is toast.

 

I do believe NAPA and other parts places carry the part.

Just did some leg work, or should I say " let your fingers do the walking"? I called 2 auto stores and they said NO to carrying the sensor. I called my local subaru dealer / parts and have one on order. Lists for $81 but since I've bought alot from, I'm getting it for 65. I'll wait till close to 6pm and test again

ok here it is 45 mins out in driveway, hood open, winds gusting to 30mph, 26 degrees here 9,500 ohms ??????

Definitely shot... I looked around at some other places, but couldn't find it much cheaper then you could get it. $65 is a good deal for it. These are kind of common to go anyway, at least I've seen quite a few go bad.

I installed the new temp sensor tonight and guess what....... my Loyale started right up so fast I'm surprised how that little sensor fixed my start problem. KUDOS TO SKIP THANK YOU SIR

BRUCE

Our pleasure sir,

glad we could be of assisatance.
