Inspection failure
 

Purchased my 2006 Sonata V6 in September, 2005. They give you 4 years on a
new vehicle here in NJ. So, today I go over to get the inspection done
since I have some time. I had to sit in line for just over 30 minutes.

I get in the facility, get out of the car, and I see the CEL come on. I
keep my mouth shut knowing they will fail me anyway. Guy gets in the car
and tries to rev the engine....nothing happens....it just idles. He puts
it in gear and it drives fine. Back in park and it won't rev up.

Now I am figuring this is some computer screw up as it has never happened
to me before. I suggest turning the engine off and then on again. He does
it. Engine now revs fine and CEL went off.

But....when they hook up the OBDII reader, the engine still tossed two
codes that they had to fail me for.

P1295 and P0638.

Now my car is still under warranty, so I am probably going to let the
dealer have a go at this one, but I would really like to know if anyone has
seen this before after a long idling period. And Hyudaitech, maybe you can
interpret those codes for me?

Thanks,
Eric


BTW, I just turned 50,000 miles yesterday...my inspection report shows
50,038 to be exact. The emission warranty is 5/60 here I think.

Re: Inspection failure
 

This is from the Hmaservice website.

2006 > G 3.3 DOHC > P0638 Throttle Actuator Control Range/Performance
Checking output signals from TPS. under detecting condition, if the
difference between real and target throttle position is above the specified
value, PCM sets P0638. MIL(Malfunction Indication Lamp) turns on when the
malfunction lasts till 1 driving cycle.

2006 > G 3.3 DOHC > P1295 ETC (Electronic Throttle Control) System
Malfunction - Power Management
If power management mode is recognized under detecting condition, PCM sets
P1295. And MIL(Malfunction Indication Lamp) turns on.


The Electronic Throttle Control(ETC) system is made of the components
throttle body, Throttle Position Sensor(TPS)1&2 and Accelerator Position
Sensor(APS) 1&2. The throttle body contains the actuator, the throttle plate
and the throttle position sensor (potentiometer), which are integrated in
one housing. The actuator consists of a DC motor with a two-stage gear. The
opening angle of the throttle valve is detected by the throttle position
sensor which is mounted on the throttle body. And it provides feedback to
the PCM to control the throttle motor in order to control the throttle valve
opening angle properly in response to the driving condition

Re: Inspection failure
 

Thanks! So they both relate to the throttle in one way or another.
This is very interesting considering the throttle problem I mentioned.
First time and only time it has ever happened thus far.

And also amazingly, the CEL went off after driving the car a few times.
I'm wondering if this was just a fluke one time thing. My appt. at the
dealer is 9/1, but I may attempt to take it back for re-inspection
before then. It doesn't hurt you here if you fail twice.

Re: Inspection failure
 

Be careful that you don't take it back in for inspection too soon after the
dealer (or anyone) clears the codes, a status is set and doesn't clear
until a number of drive cycles have been driven. This status will also
cause a rejection. This is to stop people from clearing the codes and going
straight to the inspection before the error can recur.
Are you saying that he failed you even though the CEL was not on, just
because he found the codes set?

No, sorry. I know what I wrote was a little confusing. The CEL was on
initially, then turned off, then apparently was on again. It was still on
when I took possesion of the car again, but turned off after a little bit
of driving. And I was warned by the dealer about the drive cycle
requirement. I am headed out now to the inspection station. All they can
do is fail me again if need be and I already have a dealer appointment next
Tuesday.

Thanks again,
Eric

Re: Inspection failure
 

The inspection station was too jammed yesterday, so I went this morning
after a midnight shift and passed without an issue. I'm probably still
going to let the dealer have a look to see if maybe it was something more
than a fluke.

The plain English translation of all this is that P0638 set and the
check engine lamp came on because the PCM perceived it was unable to
move the throttle plate to the desired position. P1295 sets when a
power management mode is entered. In this case, because the PCM
detected a problem with the throttle body, it limited engine rpm to
prevent uncontrolled acceleration. There's a technical service
bulletin regarding this problem. It instructs the technician to
replace the throttle position sensor and reprogram the PCM. If you
haven't done this already, have it done soon. The car isn't very
driveable when the problem occurs.

Thanks, HT. Haven't seen this TSB. Will look and get it applied soon.
