Technical Revs

[NebulaStilo]

So i decided to open my car just from pull away and when it got to just over 5000 rpm it limits. Like it won't go passed that rpm. Is it a limiter or fact that I need to change O2 sensor (according to ecu)
Thanks

Is it a Diesel ?

Is it a Diesel ?

No.
Its a 1.6 16v

5000 sounds a little low to me.

My 1.4 petrol revs up to 7000 a then hits a noticeable limiter in the red zone. But goes past 5 no problem... In all gears

Check the Throttle is fully opening.

Sometimes extra mats and stuff can stop you putting yer foot fully down.

I checked diagnostics and she telling me I have a faulty oxygen sensor. Could it be that?

Oxygen sensor tells the engine how much benzina to stick in there... so if it runs out of puff and you have a faulty sensor, there is a good prospect that the two conditions are linked.

If it's not the sensor, then it would be a fuel delivery issue but more things have to go wrong for that to be the case, than for a single sensor (which you already know is faulty) to fail.

Regardless... you went to some trouble to get the diagnostic reading kit and then probe the car's brains for errors.. so whether the sensor is the cause of this problem or not... I don't understand why you haven't replaced it already.

A sensor is out of my budget at the moment.

It's very expensive by us in SA.
My usual parts supplier and they have stock of all car brands ,they don't have my sensor. I'll have to buy it off eBay over the next month or 2.
