Oxygen sensor
I`ve ordered universal Denso
I`ve ordered universal Denso sensor DOX-0109. It is half cheaper than dedicated sensor. The only different i see ist that dedicated has an connector and universal doesn`t have. I hope it will work... I`ve damaged heater of sensor DTC P0135.
PrimeChoice - KO-0138
Last Friday, I replaced the O2 sensor on my 1998, 1.8 GDI JDM Pajero iO with a Prime Choice KO0138 acquired from Amazon in the US for the handsome sum of USD$28.11 - during the six days since the replacement, I have used the vehicle daily and consumed just less than a half tank of fuel, which is significantly less than it was using before the sensor was replaced.
The KO0138 is supposed to be for a 1.8 MPI Carisma, but it appears to work just fine on my 1.8 GDI Pajero iO and has the added benefit that it plugs right in - no fooling around with splicing wires or getting them connected wrong - in fact the only additional step I needed to take was to transfer a nylon tie down from the old sensor cable to the new one so it clips to the metal bracket that the connector snaps on to.
By the way - Mitsubishi lists this part as MD359910 at a whopping USD$454
Just filled the tank after a week's use.
Fuel here is $217/litre (around USD$1.08), I just filled the tank adding 24.7 litres, having driven 223.5 km (all city driving), so I'm looking at around 11 litres/100km, not too shabby in my opinion - I've seen it as low as 14.6 litres/100km, so I'd say there's been considerable improvement. There may be room for more, and I will be watching the coming week with interest, as I have just changed the plugs,
im thinkking of getting a new
im thinkking of getting a new O2 sensor as well and i found this

also if you change the model to mirage you can find the 1.8L 4g93 engine

hi, FORDEM... me again, abusing on your good will (uh... shame on me)...
How did you know you had to replace your O2 sensor (called here as "lambda sensor")?
Is it hard to do it?.... At Rockauto I got some nice prices, for the 4G94 Tr4's engine,,,
Thanks in advance... again,,,
Cheers!
Forums are about people helping people -
In my case I had ridiculously high fuel consumption and an exhaust so rich you could probably light it if the cat wasn't there to burn off the excess fuel - I went though the other sensors, one at a time and verified them as functional - the O2 sensor test didn't seem to work like it should, and when a friend told me that the O2 sensor was a service item that needed to be changed at intervals (this is my first vehicle with an O2 sensor), I decided to go ahead & change it, and see how it would affect the fuel consumption.
The car now burns maybe half the fuel it used to - possibly less if you're on a long run - and whilst there is still quite a bit of soot on the plugs, the exhaust no longer smells rich after the engine has warmed up.
Changing the sensor was very easy - at least in my case - I bought the O2 sensor, a "crow foot" style 3/8 drive O2 sensor socket, and a "thread chaser" to clean up the threads in the sensor bung. I've read lots of horror stories about people having to heat their exhausts and destroy old sensors to get them out, but I just applied liberal amounts of WD40 to the sensor with the exhaust hot when I parked the car for a day or two prior to the removal, and when I put the wrench on it, it came out very easily.
Upstream is before the cat
Upstream is before the cat (closest to the engine) and down stream is after (furthest from the engine).
Where did you guys find the tr4 on rock auto? Could you send me they link? Might be where I live but I can’t find it for the life of me.
RockAuto
RockAuto is essentially a North American site - US/Canada/Mexico - since the TR4 is unique to Brazil, you won't find it listed there. If you know the Mitsubishi part number, you may be able to look that up and find an equivalent for a US model Mitsubishi on RockAuto, but you can't search for TR4.
Upstream/Downstream
Hi guys,
Can someone explain to me the upstream and downstream for the oxygen sensor? I have a 1998 Pajero iO with the 1.8L 4G93.
Thank you,
First - upstream & downstream are going to be OBDII vehicles only, and I am not certain if there were ever any OBDII Pajero iO built.
As mentioned previously, the upstream oxygen sensor is before the catalytic converter, and is the one used to set fueling, if your iO has fuel injection (not all of them do), it should have this sensor, the downstream oxygen sensor is after that converter and it's purpose is to monitor catalytic converter efficiency - if the catalytic converter is doing its job, there will be less oxygen in the exhaust stream after the converter, so what the ECU does is compare the output of the two sensors, if the downstream sensor is showing a similar reading to the upstream sensor it will set a catalytic converter below efficiency threshold message.

Ask me in a month
I have just ordered an oxygen sensor for my iO - it's at my daughter's apartment in Florida and I should have it in about two weeks.
It's supposed to be a direct fit replacement for a Carisma with a 1.8 engine, rather than a 1.8 GDI iO - so I am taking a chance on it - based on the advice of a friend who designs ECUs for a living, he says any universal should work.
