has anyone tested the newer bosch o2 sensors that are supposedly designed for honda?

not the universal ones?

they seem to have new packaging and possibly close to oem specs.

i know there was someone that tested bosch sensor vs oem found out that the voltage output was offset and the frequency was not correct.

but that was so long ago.

yet everyone keeps recommending ntk oem etc

so has anyone tested them to make sure the old tech is still true?

I have never had a problem smogging a car with bosch O2's. Frequency depends on the scan tool refresh rate.

As with any O2, soldering the wires will increase signal accuracy.

OEM is always ideal as it is what the car came with, but I have never seen a car fail smog because of Bosch sensors.

well last time i used bosch it was pretty bad gas mileage. it passed smog but it wasnt working right. i switched to used oem sensor and it started working much better.
but this one seems to work ok

O2 sensors are calibrated for specific engine and ECU/PCM combinations. This was the main reason that the "universal" O2 applications faired so poorly. If Bosch has some that are application specific, I imagine they should work fine.......

If the "new" version is the one that was out when I bought mine last year it lasted for 11 months before throwing a code 43. It was Honda specific supposedly but the sensor itself looked different than the NTK. No clue on voltage readings but it never ran quite right with the Bosch that's for sure. Replaced it with a NTK and it's been good since.

How will soldering help? A properly soldered joint WILL have increased resistance VS a PROPERLY crimped joint. I do a lot of hobby/micro soldering on the side. Resistance is NEVER lower on a soldered connection than on a PROPERLY crimped one.

slowcivic2k

Your resistance will be lower on most small gauge solder joints, provided you clean and use a good solder. (silver base preferable) Because of the environment that automotive wiring lives in, a properly soldered and sealed joint will outlast any crimped connection, as soldering does not suffer from creep over time. For very large gauge wires where soldering is not effective, either due to current flow and heat or the inability to produce a good joint altogether, hexagonal crimpers will produce a very low resistance when done CORRECTLY.

Bachelor's Degree in Electrical Engineering if you are curious.

Solder also does not flex and does not fair well in a harsh environment such as vibration and constant movement.(where automotive wiring lives in) For this reason there is NO OEM that recommends soldering for repairs. A joint (crimped) connection with heat shrink is the preferred method.....

A properly crimped connection will create a solid state cold weld with no more resistance then the wire itself has. Look at your cars wiring harness sometime. Notice all those beautiful crimps? The propblem lies with people using crappy connectors and Home Depot crimping pliers. An improperly made joint will fail regardless of whether it's a poorly crimped connection or a cold solder.

I love solder/soldering... not for 02 wires though.


Real world experience in micro soldering sensitive R/C helicopter components where voltages are measured in thousandths of a volt if you are curious.


Furthermore the average joe H-T user will NOT create a proper solder connection. 8/10 times it'll be cold due to moving the wires while heating or cooling or not heating the wires directly and melting the solder onto them instead of the iron.

who give a **** this thread is not about soldering or crimping. make your own post if you want to argue about it

Remember, there is ONLY one right way to do things...... lol

When Denso sensors are so cheap and they are basically factory replacement why bother with anything else?

autozone only on order for denso when you need one asap bosh is whats available

HondaPartsHero

Try it and let us know

i put it in few days ago but found the exhaust leaks right after
and i wouldnt have any way to test it besides what shows in neptune rtp

Just go with Denso, got mine for like $16. Sure helped my mileage a little more.

where the hell you get it for 16 bucks?
