Primary O2 Sensor

[Modmedia]

Okay, so as most of you know my old engine went kaput and I bought Ollys.

It's all fitted and running but the tuner said that there is an error code and he believes I should replace my Primary O2 sensor. I asked if this code was because I had a Toda Manifold and therefore no cat. He said that it would be the post cat sensor that would be affected by that (so I bought a spacer which is on the way)

Thing is, he says if I don't get the Primary O2 Sensor replaced asap it may cause massive damage again? Is this true, if so, where do I get one that is a bit cheaper than Honda? And do EP3 aftermarket ones work (for example NGK)

Cheers.

Yeah if you have a toda mani then the post cat sensor will flag up a error code but i wouldn't worry about that.

If the primary sensor is damaged i would replace it asap. Will lead to poor performance and poor MPG

Needing a new primary O2 sensor should mean your car is running in limp mode. It's perfectly fine to drive your car in this state whilst you sort out a new sensor.

Personally I would only get a genuine Honda O2 sensor as they are the only ones that work 100% of the time. The others are a lottery (even NTK!) whether they will hold up e.g. Failing after a few days or weeks.

Has he tested the 02 sensor to check it's operation? It he has and it's faulty then replace it with OE. If it's stuck rich/stuck lean then it could lead to a bigger problems. Most of the time the fault is just with the heater circuit though.

Any ideas if the ep3 ones are the same as the dc5 ones?

Different. Wideband in DC5, Narrowband in EP3.
