just a quick one, am i right in saying the sensor in the exhaust system just after the turbo on a 1994 starlet gt is a temp sensor not a o2 sensor?
cheers

The second one is the cat temp sensor

with one wire though?

yes

so i should get a voltage reading from it so can use as a air/fuel check?

i dont believe its needed as most of them get removed when using a decat pipe

the first sensor for the turbo is the o2 sensor and no its far for the best way of checking ur air/fuels

if was to fit a air/fuel gauge would a replace this sensor with one with 3/4 wires then?

Yes, you need a wideband sensor, the stock one is narrow band
sensor...
1. i had swapped my 4efte to 4efe. from the old 4efte manifold, there was a sensor that located on the cat. what sensor is that?
2. after i swapped to 4efe, i still using the old exhaust but as i noticed the mechanic did not install the sensor back because of the cat has been removed and he made a simple pipe joint from the manifold to the exhaust. will it effect my engine? the performance? my fuel consumption? air mixture?? or, there will be nothing wrong leaving the sensor just like that?
so far the car runs ok. but i feel the fuel consumption is quiet high. and when i switch the aircond my rpm will increase from 900 to 1100rpm. can anybody explain it to me? thanks...

The sensor before the cat will be the Lambda (O2) sensor, the one after it is the temp sensor. I'm not sure about driving the 4E-FE without the Lambda sensor, but it's certainly possible on the 4E-FTE.

Post some pics of your current setep.
Not necessarily, the sensor could be using the cat itself as earth (As the Lambda does)

engine rpm will go up slightly when air conditioning compressor clutch cuts in, this is normal for most cars.if it doesnt increase engine rpm car would probably stall due to load from compressor when it cuts in. so if you are using air cond all the time mpg will go down.
dont know starlets setups well enough to comment on leaving exhaust sensor disconnected, normal cars have 3/4 wires for o2 sensors, these would confuss emissions, give running problems etc on those cars if were left disconnected.
