How do I clear the code for the check engine light in a 2006 Kia Sedona

SOURCE: Engine Check Light - 2006 KIA Optima

Hi

Before you turn out the light you should have a code read carried out just to make sure nothing sinister is going on with the management system.

If the car is running ok then the code will probably either pertian to the O2 sensor, the EVAP system, or a drop in catalytic efficiency, but this isn't set in stone, just the most popular scenarios.

Very best regards

that code definition is "Evap high purge flow fault". It means you may have a problem with the evaporative system. this system routes fuel fumes back to the fuel tank. If you want to try and clear this code, find the radio code for your car and then disconnect the battery for 30 seconds. Reconnect the battery and the check engine light should be out. You will then need the radio code to reset your car stereo. the check engine light may stay off if the condition was a transient one. If not, the light will come back on after you drive the car two drive cycles. That is: two starts, warm ups and shut downs. If the light returns, have a mechanic check it out.

A code p0455 most likely means one or more of the following has happened:

• A loose or improperly affixed gas cap
• A non-conforming gas cap (i.e. not factory/original brand)
• Other leak or damaged piece in EVAP system

• Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
• Otherwise, replace the gas cap, and/or
• Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

Congratulations! You have discovered that clearing codes without diagnosing and repairing the problem that caused the code only results in a repeat repair! You now know more than half of the "mechanics" out there.

OK, on a more serious note: First we have to get the codes straight or get the car straight...I'm pretty sure it is the code that is not correct....Code P0431 and/or P0430 are not valid codes for a 2006 Pontiac Gran Prix GXP. Those are evaporative emissions system codes that do not apply to your car. However, since you mentioned "cam sensor circuit", I will assume at this point that you meant to say P0341 and P0340....BIG DIFFERENCE!

The next problem is that although they are very similar, the troubleshooting charts are different depending on whether your GXP is equipped with a 3.8L engine or a 5.7L engine. If you want help with a problem like this it is REALLY IMPORTANT that we know what we are working on. Otherwise, you may get some VERY GOOD information that does not apply to your vehicle and the "expert" will probably be thought of as "incompetent" for giving you bogus advise. Then comes the bad ratings, and no testimonials, etc. and it wasn't the expert's fault he didn't have the correct information to work with!
It's just not FAIR!!!

ANYWAY.......

For either engine, Diagnostic Trouble Code (DTC) P0341 is not necessarily a "Circuit" problem. Although it may be) This code is usually caused by mechanical failures - See the list below.

CONDITIONS FOR SETTING THE CODE
1. The PCM detects the following every 2 engine revolutions:
. A. 36 medium resolution engine speed signals
. B. 6 low resolution engine speed signals
. C. More than 1 cam sensor signal (herein lies the problem - there should be only one)
2. The conditions in item #1 above are met for at least 4 consecutive seconds.

When the conditions above are met, the PCM sets a "Pending" code for the current drive cycle. On the second consecutive drive cycle that that the same conditions occur, the PCM will store a memory code and turn the Service Engine Soon or Check Engine light on. This explains why it takes a couple days for the light to come back on...It takes a minimum of 2 drive cycles to turn the light on. If it fails on this drive cycle, and not the next, the counter starts over. It could conceivably take weeks or even months for the thing to fail two times in a row if it is an intermittent problem.

If it is failing on a regular basis, the conditions (or causing symptoms) can be verified by using a lab scope and tracing the cam sensor signal and the medium or low resolution engine speed signal. Just count the pulses - if there is more than one cam sensor pulse for every 6 low resolution pulses or 36 medium resolution pulses, the problem has been verified. Now, to find the actual CAUSE so we can fix it.

The most common cause of this is miss-routed or bad ignition (spark plug) cables that are "spiking" the cam sensor circuit.

This code can also be caused by:
Camshaft reluctor ring damage
The cam sensor coming into contact with the reluctor ring
foreign material passing between the reluctor ring and the cam sensor.
Wear or damage to the timing chain, timing chan sprockets, or timing chain tensioner
Excessive camshaft end play

Now DTC P0340 is really the opposite problem.
If your car is setting both of these codes at the same time, you have a really erratic cam sensor signal that should be VERY easy to verify with a scope.

DTC P0340 sets under the same conditions except instead of having more than 1 cam sensor pulse, there are NONE.

This code is usually caused by the cam sensor itself, however it can also be caused by the circuits to the cam sensor. The integrity of the circuits should be verified before replacing te cam sensor for this code.

SOURCE: changed the TPS on my 05 sedona and it reads P0122

this code may cause by:

TPS not mounted securely.

TPS circuit short to ground or another wire.

Faulty TPS.

Damaged computer (PCM).

to fix this code you can try this:

Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.
