My wife had a 2008 Hyundai Santa Fe 3.3 V6 and it went into limp mode while I was driving. Top speed about 10 MPH. After restarting, it behaved normal. After it did it again, I replaced the TPS. May have only been a connection issue, especially since I routinely clean the engine.,,but it had about 120,000 miles on the odometer.
Not wanting to experience limp mode again, it was best to replace it....no tests done other than using my OBDII plug-in unit.
However, with a fairly new TPS (age or miles), with little operation to damage the internal wipers, I remain skeptical that Keihin produced very many defective units.
I have not opened one, but expect the wipers to be redundant several times over *. Failure could occur if
a. All the wipers broke or lost spring pressure
b. Resistor damaged/worn
c. A lot of crud inside.
* The industrial automation company that fed my family for decades built systems to assemble and test several automotive sensors. All the ones with moving parts for variable resistance had multiple wipers (contact fingers).
Again, since the issue is intermittent and with sensors relatively young, I would thoroughly check for good connector connections.

If you still have it????......
A good Hyundai tech and a friend of mine told me this::
Some Santa Fe with 3.3L engine may experience a MIL with the ETC (Electronic Throttle Control) system-related DTC P2135
-P2135:Throttle position sensor 1/2 voltage correlation) or P0110 or P0128 P0300 or P030X or P0638 and others.
An improved Throttle Position Sensor (TPS) and ECM software upgrade or complete updated throttle body are available to resolve this condition.

Thank you much, but we traded it on a Nissan Frontier SV 4WD, June 2016, right after a cross country trip to see our daughters in Georgia. It had well over 140,000 miles and was running quite well...but one snow storm kept us from driving the last ~1/4 mile to our Arizona ranch (Jeep trail) and we needed 4WD.
Other than a minor issue with one of the dual fuel level sensors and the TPS, it was faultless. Did not even need brakes until ~105,000 miles (mostly long distance driving) and was on the original NGK platinum spark plugs.
OK, I guess I sufficiently contributed to thread drift.
