I thought I was getting bad gas mileage, but check engine light wasn't on.
But I went to ORileys to use there code scanner to check for any codes.
Turns out, check engine light bulb wasn't working, but I got a code, P0155

p0155, has something to do with the o2 sensor
02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)

my exhaust manifold is cracked, so that could be causing the issue.



i checked the prices for a new exhaust manifold and the cheapest i found it for was for about $267

I was looking to just replace my entire exhaust system, because its cheaper, i found exhaust kit for about $175 on eBay
The exhaust kit comes with headers though. and it has the hole for the o2 sensor.

would this be a better route to go to save money?

Add car/engine information - Read the forum Rules sticky.

And fix your CEL. You appear to have known it wasn't working for more than a year.

This is a different honda. I don't have a 98 Civic DX anymore RonJ

This is about a total different topic.

The question was if replacing the entire exhaust system would be a better choice, seeing that it cost less than just buying a new exhaust manifold


RONJ, I've only had the car since October....?

Whats the freakin car? If its not a Honda than what is it, a scooter?

So then why did you fail to add the required car information when you made this thread? This isn't your first thread. Follow the forum Rules.

The reason your manifold is so expensive, is because it has an integrated catalytic converter. Those cheap eBay exhaust systems do not have a catalytic converter in them, which may cause you to fail inspection depending on where you live. Driving without one is also federally illegal (granted, if you have feds under your hood, you have bigger problems, but still). In the long run, piecing together a proper, functioning full exhaust will be more expensive than replacing your exhaust manifold/catalytic converter combination, and sticking with the OEM setup (which, again, cheaper in the long run) will also maintain the factory quiet exhaust sound. Those cheap eBay kits almost always have bigger pipe diameter, a shitting "N1 style" muffler that's loud as ****, no resonator, and no cat.

if its auto, he can get away with the dx unit. auto hx uses a 4 wire primary and secondary, manual has the wideband

Matthew98DX

Yeah i found this one for way cheaper than anywhere else!

Will this one work?
Yes, my HX is automatic.

Now when i go to replace my O2 sensors, its better to just replace both at the same time, are these the ones I should be looking at?
I called Advanced Auto, and they something about having a CVT transmission, I need to buy a certain o2 sensor, the guy i talked to was very confused.

I posted a picture below.

I'll just skip out on buying the exhaust system. Yeah I forgot they don't come with a catalytic converter. I would have to buy one. I checked Orileys website, cheapest I saw one for was 190$, and that's on top of the $170 for the exhaust kit. By the time I do all that, I'm spending over 400$ on a exhaust kit.
Thanks for looking out for me

the auto hx uses a 4 wire primary oxygen sensor or "upstream". the secondary or "downstream" you posted is correct, the primary looks ok as well.

Matthew98DX

Alrght cool.

I'mma gonna head over to Orileys and pick up theses parts.
Hopefully they will be able to price match RockAuto!
