A little more painful tonight ........ the fix appears to have failed. Both the check engine and ESR light are again on. Another crappy trip back to the stealer.
TPS SENSOR, Symptoms of TPS failure CEL, ESC OFF LIGHT ON=TOTAL LOSS OF POWER
KIA SEDONA 2006>*2012
HYUNDAI ENTOURAGE 2007>2008
Most likely most all KIA /Hyundai's that don't have a physical throttle cable.
Hello all, (part of) the below post was originally going to be part of a reply to a post in another thread.
Thought I'd expand on that post, and post it here so it would help others..
EXPERIENCING ALL OF THE SUDDEN A TOTAL LOSS OF POWER?
Most likely it's the TPS SENSOR
(TPS= Throttle Position Sensor)
Current part #35107-3C100-NFFF THROTTLE SENSOR ASSYS (TPS)
(If you haven't yet had the below experience, don't worry you will, it just a matter of time.)
TPS SENSOR, what's that?
Back in the old days- A cable was attached to the gas pedal- when you push the gas pedal the cable would open the "butterfly, aka Intake plate". The further you push the gas pedal the more air is admitted into the engine, and the RPM's increased. (Car goes faster.)
Sedona/Entourage has No throttle cable.
It has what is called a "fly by wire" system.
You have a switch in the gas pedal that "talks" to the TPS, and the ECM /ECU. The ECM/ECU (computer) tracks position of gas pedal, and the TPS tracks the position of the intake butterfly valve (Stepper motor). If they don't match... the car goes into "limp home mode". (RPM drops to idle)
SYMPTOMS OF A TPS FAILURE=
You lose power ALL of the sudden without warning (Cool I need a challenge today)
"CEL" comes on (Check Engine light) Code=P2135 IIRC
ESC OFF light comes on (Electronic Stability Control)
Car loses ALL power and the gas pedal doesn't do a blankly-blank thing. (Cool, Hey look at that dump truck coming right at my door - GEE, I can count the number of fins on the radiator it's so close.)
RPM= Think idle speed...
If you are early on in this "lovely" adventure (EG: It just started to happen)... turning the car OFF, then recranking the car will "reset" the ECU... and you regain power.... Regain power till the next event occurs that is.
This morning wifely called... (Boy did she sound happy) dang thing screwed up on her about 4-5 times on her (3) mile trip to work.
Well depending upon the *age of your car you can't just "replace' the TPS sensor as they've superseded the part number and it requires that the computer which talks to both components has to be "updated'.
(Read that as you have to pay the dealer 1hr labor -on a part that can be replaced in a few minutes.)
* 2011? 2012 models...
Disclaimer" I don't know when the superseded part came out so a 2011? 2012 model may have the revised part already, If so the symptoms will be the SAME, lucky for you no ECU "update" is required
NOTE: If your car doesn't require a ECM update replacing the TPS is a simple DIY repair.
The holes that hold the TPS sensor are NOT slotted- remove the (3) bolts, (1) electrical connector and it comes right off.
Price= 1hr labor (To R&R TPS SENSOR and REPROGRAM ECU)
(Price was also 1hr labor if I installed part- and had them reprogram ECU)
Total cost= 1hr labor+40+/- for TPS itself...
TIP: If you're car is having this problem, Pick a time of day that traffic is light. If you attempt a trip to the dealer in rush hour traffic you will have all kinds of people using various hand gestures directed towards YOU.
Ah, the trip to the dealership:
Oh, the trip to the dealership was FUN, imagine going city block by city block stop and go NEVER knowing "when" it's going to lose power...
(Lost power about 10 times on the way over there.)..
Once I got on the interstate (A crap shoot if it totally crapped out) When I did have POWER,, it was like get the HECK OUT OF MY WAY... I need to get up SPEED to make it up the next HILL (Mountain) if this thing fails on me again.
(Man was that a police car I just passed?...)
NOTE to self,,, lucky SOB's in areas with their flat level ground -Long stretches of flat level road...
Oh, to the lady in the Honda that was getting off the interstate talking /texting on the phone going like 15mph and when I went into the far lane to get around you, "then" you tried to come over on me...
GET OFF THE PHONE AND DRIVE !!!!
GET IN THE SLOW LANE, its' not cool to block faster traffic (She was going like 15 in a 45mph zone)
