my dad's 96 GLE had the CEL (Check Engine Light) on so I did the .org method, counting the # of long and short pulses..
so after triple checking it, i got 0505 (No Failure Recorded/Detected)

My friend told me his CEL was on and he went to Autozone and they checked it for him for free.. So i went and did it myself
and i had three problems:
1) P0325 - Knock Sensor
2) P0446 - Emission Control Vent system (need a new Gas Cap)
3) P01400 - Auxillary Emission Controls (EGR circuit needs to be cleaned)

SO maybe you should find Autozone and ask them..

 

and they asked $164 for a new Knock sensor.. can i get it cheaper somewhere else?

 

brand new $90 bucks shipped on ebay http://cgi.ebay.com/ebaymotors/ws/eB...tem=2450815316

(click above). This is where I got mine.

 

ebay 90$ shipped

 

i beat u kevlo

 

how about Auxillary Emission Controls ? the guy at Autozone said that either the EGR circuit needs to be cleaned or i have to get a new one.. but their computer did not list the price.

 

i heard they are not complete with the codes for other gens though.

 

P1400 - 1005

do you have a haynes manual ? or you can use the online chiltin manual link found in the faq's


1005
1005 is EGRC Solenoid valve

The majority of my information about Diagnostic Trouble Codes comes from my '99 Maxima factory service manual. Unfortunately, DTC 1005 is not in that book. Starting in '99 the Maxima engine uses a step-motor type of EGR valve and with that change, the DTCs changed.
The Chilton and Haynes manuals provide a little information about the EGR Solenoid Valve.
The test procedure for this part is found in the Chilton repair manual (page 4-11) and the Haynes repair manual (page 6-20). Test the valve and replace if necessary.

This malfunction is not an emergency but should be resolved fairly soon (7-10 days). An inoperative EGR valve may result in engine pinging and a variety of driveability complaints.

 

Here in California they are not allowed to check the codes anymore. They and Kragens use to do it for free, but when my sister took her 2000 Maxima when she had a CEL, the employees at both place said that they could no longer do that due to California law. It ended up being an O2 sensor. She had the extended warranty at the dealer, but she wanted to know what it was before she took it in. On her car the CEL can't be read or reset like on our cars, it has to be hooked up to one of the scanning machines. Next time I go by one of those places I will ask exactly what that law is.

 

If AutoZone doesn't do it b/c of the CA law, go to a small shop that gives a free estimate. They'll check the code for free

 

I will keep that in mind, in case my sister's Maxima gets another CEL.

Thanks JaTan

 

No prob

 

dont waste money on the KS yet....just correct the other 2 problems first, and hopefully the KS will just be a ghost code

 

so how much should my dad expect to pay? including labor.

 

that law is probably just another way for you to spend money by being forced to take it to a stealership or shop, lol.. i dunno, just my $.02
