2007 hyundai sonata with man. specific code of P1295, other codes are P2106 and P2135

Hyundai released a technical information bulletin regarding P2106 and that should be addressed first, if you can find it.

When the check engine light is switched on it means the closed loop system is switched off and the engine is running on the get-you-home programme.

The codes you are reading are manufacturer specific and better results are usually obtained using dealer level diagnostic equipment.

Sometimes the codes don't clear themselves after a repair. If the codes aren't erased the brain assumes the faults still exist. Throwing a new part at a problem before knowing the part is faulty is expensive, especially when the code could be caused by poor connections or wiring problems.

enginecodes.com will tell u what those codes mean. then start at the beginning and go to the end fixin as u can. I had the same problems all last summer .lol.

With regard to the P2106 and P1295, while it is true the ETC is part of the system that can trip these codes, it is only one part of the system. It also incorporates the pedal position sensors, wiring, PCM and so forth.

P2106 is throttle actuator control system-forced limited power
P2135 is throttle / padel position sensor A/B voltage correction

as for the last code well i have never seen it

sounds like fuel built up inside your exhaust before the cat then it ignites creating a bang. insuficient spark or timing...

Hello, There is not a recall for this issue,but there is a TSB (technical safety bulletin) by Hyundai for this issue that you are having with your vehicle for the code that was set. What this consists of is replacement of the throttle position sensor and performing an ECU software upgrade for the vehicles computer. The process usually takes about 45 minutes to an hour to perform at a Hyundai service department. If you are the original owner of the vehicle or it has less than 60,000 miles, this repair procedure is no cost to the owner. Hope this info helps. Gabe

DTC P2135/P0638 OR COLD ENGINE RPM

FLUCTUATION - TPS REPLACEMENT &

ECM UPDATE

NOTE:

This bulletin revises TSB 09-FL-003-2 to add the Genesis Sedan (BH)

model to the applicability list. It also provides instructions to select the

most recent available ECM Update Events #166-178 or any higher event

numbers if they become available in the future.

DESCRIPTION:

Symptom/Condition:

Some 2.7L, 3.3L or 3.8L engines in models identified in the applicability list may

experience one or more of the following conditions:

• DTC P2135: Throttle position sensors 1/2 voltage correlation

• DTC P0638: Throttle actuator control range/performance

• RPM fluctuation while engine is cold (DTC not set)

NOTE:

Should either of the above DTC occur, the vehicle would have operated in

limited power "limp home" mode and stored the following DTC in the ECM:

• DTC P1295: ETC System Malfunction - Power Management

• DTC P2106: ETC System Malfunction - Forced Limited Power

APPLICABILITY:

• 2007-2009 EN Veracruz

• 2007-2009 CM Santa Fe

• 2006-2009 TG Azera

• 2007-2008 EP Entourage

• 2006-2009 NF Sonata with 3.3L Engine only

• 2009-2010 BH Genesis Sedan

These codes indicate your accelerator position sensor has malfunctioned. The computer has gone into limp mode, which allows you to drive to safety without damaging the engine. The computer is unable to determine how far you are depressing the accelerator and doesn't want to over-rev the engine. You need a new sensor.

TSB # 08-FL-004-1 CHECK ENGINE LIGHT P2135 DTC DIAGNOSIS....
there is a problem with the pedal assembly which has your throttle position sensor causing the codes, dealer only part you can install yourself with some know how

these codes have to do with the corralation between the pedal and the throttle sensor module on the engine. You will need to get it doagnosed to find out what is wrong since the usual culprit cost several hundred dollars.
