Went to get free diangostics and told me about tps sensor

make, model, year?
get trouble code from auto parts store that will do it free
suspect tps (throttle position sensor) if scanner found none
other suspects: vehicle speed sensor, engine revolution sensor, ecm or pcm

This info is from 1998 Saturn Sl , my service info doesn't go to 95 . It's the same except for code numbers , My info is P0xxx #'s . The quad driver is part of the ECM - engine computer !
Here is a description from Saturn service info .
A quad driver module (QDM) is an electronic switch which completes a ground circuit when switching ON. The QDM independently controls 4 separate outputs. A load is connected between battery voltage and the QDM allowing the QDM driver to control the output. Each QDM has fault detection logic which compares QDM driver input and output voltages. The logic expects to measure less than 3 volts when the QDM driver is ON and greater than 7 volts when OFF. The QDM has only one fault line that will detect a fault on any of the 4 outputs. The scan tool can be used to cycle the outputs ON or OFF. The scan tool can also perform an automated test which can isolate the faulty circuit.
The quad drive it self may be bad , GM had a problem with these !
Did you check fuse's ?
Conditions for Setting the DTC
DTC P01650 and/or P1651 will set if:
?€¢
There is an open, short to ground or short to voltage on any of the QDM output circuits

?€¢
MIL (SERVICE ENGINE SOON) telltale circuit

?€¢
Upshift lamp circuit

?€¢
Cooling fan relay circuit

?€¢
A/C relay circuit

?€¢
Fault detected for 5 seconds for DTC P1651. Fault detected for 20 seconds for DTC P1650.

Important: The QDM circuit is continuously checked when the engine is running.

engine check light should be on
check theses things
engine timing
idle control valve
TPS
crank angle sensor

change the evap sensor the location of the sensor should be on a sticker schematic under your hood

The 04 Santa Fe came with three different engines. 4 cylinder (2.4 lit), and two different V6's (2.7 lit & 3.5 lit). The 2.4 & 2.7 use throttle cables connected directly to the throttle plate, but the 3.5 uses ETS (Electronic Throttle System) which uses two sensors (APS & TPS) and a control module (ETSCM). APS=Accelerator Position Sensor, TPS=Throttle Position Sensor, ETSCM= Electronic Throttle System Control Module. There are different diagnostic procedures for each system.
Go to www.hmaservice.com and register your vehicle by VIN #.. you'll then have access to wiring diagrams, shop manuals, service bulletins, campaigns, illustrations and procedures, etc.

Check the idle air control (IAC) sensor and the throttle position sensor(TPS).

It sounds like you have a faulty TPS (throttle position sensor) sensor, it is an easy fix, and you can get the part from any auto parts store. The TPS sensor is located on the throttle body, and it is held in place with 2 screws and has 1 plug to it. Before you change it, make sure that it is plugged in. Mine did the same thing and somehow the TPS had came unplugged, so I plugged it back in and the issue went away.

I would think that you would realize, that
you have to find a repair shop to resolve
your issues, as you don't know the technology.

There is a big difference between a $75.00
TPS Sensor that is a common failure and an
ECM (computer) that doesn't fail hardly ever

You obviously should have had a quote
or a guess for diagnostic time and a price
for either issue

The VSC has nothing to do with the O2 Sensor,TPS Sensor or EGR Valve.

I will not express what I'am thinking,but in reality,NO Diagnostic work was done
on your vehicle.

My advice,and I don't know why the pros aren't all over me yet,is never go to a dealer.
You and thousands of others on this site alone,are perfect examples of why you
go down the street, to a local repair shop that cares.
I bet if you checked your in & out milage, that they are the same. Never road
tested,nothing,just threw parts at it at your expense.
There are good techs at dealers,but no service Mgrs that care,it is all about
taking your money and selling services you don't need. On the 5th visit they will
make the drivability repair you went there for.

Common sense: asumming they pulled codes
you never have multiple sensor failures all at one time.
