Hi, I'm in the need for a new oxygen sensor to fit my '95 214 SEi.

Been informed that the correct part number for my car is the MHK10004. Will an oxygen sensor from a 95-99 400 MK2 / 200 MK3 (part no. MHK100840) fit my 214 SEi, as the engine and ECU is virtually the same? Is the connector plug the same?

Thank you.

I'm not sure to be honest, however there are lots of aftermarket sensors out there that fit fine and cost rather a lot less than the rover price usually!

Are the aftermarket sensors really effective?

Some guys warned me they were not accurate and reliable so I should get an original replacement part.

If you're able to wire the plug onto a new sensor yourself, you can save a lot of money simply by buying a sensor for universal use from Bosch or NGK. These would come with 4 wires which need to be connected to the original loom of the defective sensor. The original sensor would be one from either company with some more wire, a plug and a much higher price...

I was looking for one for my Honda engined car: Nearest Honda dealer (No Rover dealers at all closer than 70kms): 160 Euro. The same can be bought through online dealers at about 120 Euros. A used one from a scrappy would be about 30. If you go and buy a universial model: 30-50 Euros for a new one and a bit of extra work fitting it.

Many aftermarket sensors already have the correct plugs attached to them so literally are just a plug and play swap. Last one I bought with the right wiring on was £40 for our old 214. Go for a recognised brand one and you'll not go far wrong.

Thank you both for your opinions.

Well, I've got the opportunity to buy a new original sensor for €60 (about £55), but it's the part no. MHK100840 to fit the K-Series engined 200mk3 and 400mk2 (mine's a '95 200mk2 214SEi). It's the 4 wire and I think the connector is the same (not sure though). The engine management is the same, MEMS 1.9 ECU in both cars.

Bosch asked me €120 for a new compatible O2 sensor, and a new original one at the dealer it's about 220€.

I don't know if the part numbers changed or not but the only difference I can imagine between the early and later cars is the length of the wire to the plug. I think all the plugs were the same and the sensor itself will be the same. If it looks physically the same then it'll perform the same when fitted to the car.
