Hey guys my VX needs a O2 sensor im pretty sure. Its the 5 wire wideband. Curious has anyone used a Bosch O2 5 wire for a the VX ??

 

Bump

 

you're pretty sure it needs an O2???

the VX ECU (P07) is very picky about the O2.
Yes it is a wideband, and it's the NGK L1H1 (or L2H2)
it is different than the bosch.

 

Well im getting a part throtle hesitation. Almost like a dead spot. Im thinking along the lines of TPS or a O2. Because when the CEL come on boom the car is normal no more hesitation. And its not as good on gas as it should be. It has new plugs,cap,rotor,dis, header new cat, new air filter,new pcv, EGR is working fine.

 

did you pull the code for the CEL?
it sounds a lot like that the VX does when the O2 is bad, but the code will tell you for sure.

 

CEL was a 13 i think its EGR valve lift. But egr will not cause a hesitation like that above 2,000 rpm. Possibly the EGR valve is over working to lean out the mixture??

 

13 = atmospheric pressure. Hope it's not that, it's inside the ECU and not servicable at all.

EGR lift = 12

it's possible that the EGR passagway is clogged, which would cause the ECU to think that the passigway is open when it's not.
ECU pushes in less fuel when the EGR is open, hesitation... till it sees that through the O2 that the A/F is wrong then it sets the CEL and it doesn't try the EGR again.

BUT it will not run the car correctly with that CEL. poor MPG and slightly lower power is going to be the result.

 

Yeah just pulled the code 12. The egr ports are clean car is running pull up on the egr a bit and it stalls out.

 

bosch should not make anything electrical for cars anymore...their plugs made my car misfire and run rich as a pig. Im sure their O2 sensors are just as good.

Use NGK only on Hondas, works perfect.

 

Yeah its too bad the 02 sensor is worth more then the car lol. As for bosch being crap yeah there plugs are crap thats been know for over 10 years in honda world. Yeah your right there 02 sensors are junk thats why everyone uses them in there WideBands.

Question is will the Bosch 02 Sensor work on the VX Not if there product is good. Soo get your dick out of this post thanks.

Back to the question

 

EG2Driver: Bosch products are not bad at all, they simply do not work well with hondas.

JDMCRX: search for the NGK L1H1, it can be found for ~$125-150, shipped.
You're obviously not a noob, so I'll simply ask... have you stepped through the Helm manual for CEL12?

 

BOSCH GET DENSO! HERE IS THE PART #NP2344209 ! GOOD LUCK!

Why is everything failing in my Jetta? Oh right its made by Bosch.

Nope did not get a chance. Was not home long enough to look for the book. Reason im asking is i have a brand new bosch 02 and wanted to see if it will work. I guess ill try it out and see what happens. VW = broken car lol.

Yes. Just make sure the O2 sensor has the 5 plugs so it plugs into your car. Im sure it will work, just don't know how long it will do that properly.

 

I'm not sure why a code 12 for EGR would lead you to believe that replacing the o2 sensor will help the problem.

???

The possible causes for the code 12 are:

EGR valve itself
Clogged EGR ports
Bad vacuum line routing
Bad EGR control solenoid in vacuum box
Wiring or corrosion on plugs in regards to the EGR system

or

ECU itself

I've got All Data and the flowchart is about 6 pages long, and requires some time to sort it all out.

Unless the 02 sensor was free I'd diagnose the EGR issue first before potentially wasting an o2 sensor in your efforts.

Reason we rulled the O2 is there vx reliese on the O2. So i checked the EGR ports are fine. All vacum lines checked out. Also when the car goes in CEL mount the car runs mint. Pulls alot harder and does not hesitate at all. I just do not have the place to work on the car right now.

 

weather prediction for your area indicates better weather for the weekend.
I'm also a parkinglot mechanic, so I know your pain. Take a few hours and run through the EGR troubleshooting guide. It will track down the problem and the car will run the way it should.

BTW, if the O2 was the problem you'd have CEL48.

 

Bump does anyone know if it will work. EGR is working fine.

 

does anyone know if what will work?

as stated... a new O2 will not do anything for an EGR problem.

 

Ok guys got a chance to tinker with it.

I did the EGR test

1 lift valve at 1500rpm car stalls out
2000rpm car stalls out

We checked the vacum source at the manifold its good.

I tripped the silinoid with a ground it clicks we get slight vacum at the EGR valve

Now we hooked up a light to the - side the driver side of the connector went for a drive light turns on at 2500-3500 rpm

Now when the light goes on no hesitation

The hesitation is at 15-25% throtle

When the car goes into CEL mod the car runs fine.

Checked codes and i got

12
Accord Civic CRV CRX Del Sol Odyssey Prelude
85-98 86-98 * n/a 85-91 * n/a 95-98 85-98 EGR Lift Sensor (Exhaust Gas Recirculation)
defective circuit or unplugged / defective sensor
* not a valid code if car is not equipped with an EGR valve (some Civic models are not)


Now i cleared the codes for the light test.

 

Back to this topic. the EGR is opening up fine. The EGR ports are not clooged.

We did a few drives with a light bulb to make sure the circuit is getting activated and it lights up well.

 

if your gonna replace the o2 sensor .. use only and only ntk pn 24300. ive tried other sensors saying they would work for l1h1 applications but they all gave me a cel. save the money and headaces.
ntk 24300
ntk 24300
ntk 24300

i got mine on ebay from quality_auto_parts . for 170

 

Hi, I have a 92 Civic VX. I replaced my O2 Sensor with a bosch O2 bought from Autozone. At the time i needed it for smog check. Without going into a long rant about how terrible the bosch o2 sensor is, I would advise not buying it.

Pros: Removed Check engine light.

Cons: 2 tries at smog test and I didnt pass. Finally the technician noticed that if exceeded a certain number or RPM or went past a certain number of MPH i would fail, so he kept within those limits.

After the test was over and i passed he asked which O2 senor i had used.. When i told him bosch he said I should have bought any Bosch O2 Sensors.

It's been 2-3 years later, (which means another smog test) and my check engine is back on which means I need another dam 02 sensor.

If my signing up for this forum and completely bashing Bosch has taught you anything is dont trust BOSCH FOR ANYTHING.
