1993 Voyager w/ 3.3 fails emissions test. Also getting code "21"

Failing idle speed emissions test. I checked the codes from the DRB
system, and I am getting a 21, which means that the O2 sensor voltage
is staying between 4.3 and 4.5 volts. Does this mean that my O2 sensor
is bad, and will it's replacement likely correct the emission problem
too?

If the sensor needs replacement, which one should I use? Bosch brand
has not had very good reviews in this NG. Which brand to Chysler use
for replacement?

Thanks,

Kirk Matheson

 

Replace the 02 sensor with a MOPAR part and be on your way!!!

Thanks Glenn. I was hoping that was it.

try a statndard o2 sensor it's less money and they are good products

 

Bosch O2 sensors are the shits, even on old feedback carb systems. I
had one that was continuously cause mixture to oscillate between too
rich and too lean. Dumping it for a Standard stablized the system and
works perfectly.

 

I used NGK in my 1994, worked like a charm. Had teh shop do it, took
more time to write the invoice than it did to replace the part. $130
ballpark with taxes. CDN$

 

Had to change the plug, Put a mopar 02 sensor in my Hyundai haha

 

US$65, eh? Beauty, eh!

 

Yes, there is nothing like taxes to stifle the economy and suck the
$$$ right out of your wallet!

I do believe the part price was about $95, then about $15 to $20 to
install, then both federal and provincial taxes...

I generally find that the shift from USA to Canada and us$ to CDN$,
along with the need for local "wholesalers" to add their mark-up as
well usually results in what appears to be a 50% mark-up. So a $60 US$
part generally runs about $90 CDN$

And, unfortunately, it holds roughly true - yet again.

 

Uh...that's called the "exchange rate.'

I made a killing buying Canuckian dollars when Bush was letting the
Chinese sink the dollar.

 

No it is NOT the exhange rate.

The exchange rate to American Dollars from Canadian Dollars is in the
range of a 14% premuim. That is, if, as a Canadian, I want $100
American, it will gnerally cost me about $114 Canadian.

So, if the sensor is $65 USD$, then the price should be no more than
$74.10 CDN$

However, the price is $95! That is approximately a 46% premium!

The problem appears to be that Canadian "wholesalers" are paying US
RETAIL prices, and then marking up to cover their operating costs -
resulting in the 46% jump in price.

If the Canadian Market had access to US WHOLESALE prices, then I would
expect to reasonably pay about $80 CDN for the sensor. So much for
"free trade". Oh yeah, right! "Free trade" under NAFTA only works if
you are the USA! I forgot, the minute NAFTA does not work in favour of
the USA, then they just dunp illegal duties on our products until we
agree to roll over and play dead! I digress.

Now it is also possible that Canadian Suppliers are simply gouging.
You never know.

 

Rockauto show the Standard sensor at less than $40 US but there's
shipping on top of that. Fedex Economy into Southwestern Ontario about
doubles that price. Then we have to add GST, PST, OPP, RCMP, etc.....I
exaggerate

You "wood"n't do that wood you?

 

Thanks for that...I hadn't realized that the C$ had stayed so buoyant
after I cashed out at C$1.10/US$1.00. I'd been used to 65¢ on the USD
for quite awhile, but Bush's bumbling regarding China sure fixed that!

 

Yeah, I remember the $0.65 days! Man that was harsh. I have friends in
the US, but it became cost prohibative to go for a visit. Taking such
a hit on our money was nuts.

 

LMAO!
