2002 Sonata TPS wiring scheme

I have an "after market" throttle positioning sensor on my 2002 Hyundai Sonata which was installed by the original owner. The wires are were cut so there is no connector and we don't know the original color order of the wires.

I need to know WHERE to locate the wiring diagram for the TPS. I've checked tons of web links but everything seems to be about replacing, tuning or testing them.

Any ideas?

How do I solve for My Hyundai sonata model 2009 code P2110 , P2118 in scaning. I changed throttle body and TP sensor. after change of these even I am getting problem in accelerator not increases above


P2110...Faulty Throttle Actuator Control Module
- Throttle Actuator Control Module harness is open or shorted
- Throttle Actuator Control Module circuit poor electrical connection

P2118 - Electronic Throttle Control(ETC) system is made of the components throttle body, Throttle Position Sensor(TPS)1&2 and Accelerator Position Sensor(APS) 1&2. The throttle body contains the actuator, the throttle plate and the throttle position sensor (potentiometer), which are integrated in one housing. The actuator consists of a DC motor with a two-stage gear. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. And it provides feedback to the ECM to control the throttle motor in order to control the throttle valve opening angle properly in response to the driving condition.

Where is the throttle positions sensor located


The Throttle Position Sensor, or TPS is connected to the throttle shaft on the throttle body.

Fig. 2: Disengage the Throttle Position Sensor (TPS) wiring harness connector

According with the Grand Cherokee Repair Manual, check this removal & installation procedure...
(see Figures 5 and 6)
  1. Remove the air intake tube at the throttle body.
  2. Disengage the TPS wiring connector and remove the two mounting screws.
  3. Carefully remove the TPS from the throttle body.
To install:
  1. The throttle shaft end has a tang that can be fitted into the TPS two different ways. Only one of the installed positions is correct. When correctly positioned, the TPS can be rotated a few degrees. To determine correct positioning, place the TPS onto the throttle body with the throttle shaft tang on one side of the TPS socket. Verify that the TPS can be rotated. If the TPS cannot be rotated, place the TPS on the throttle body with the throttle shaft tang on the other side.
  2. Tighten the two TPS mounting bolts to 60 inch lbs. (7 Nm) and engage the wiring connector.
  3. Manually operate the throttle and check for any binding.
  4. Install the air intake tube.

Car engine shuts down while driving and will not restart. Diagnostic machine displays code 1701.


Hi,

On a Hyundai this error code indicates a a faulty TPS (throttle position sensor). You will have to replace it as the circuit is open and it is faulty.

Fix the Throttle position sensor first, then see if things settle down, without that input, computer has to guess.

Got a p2110,p2118,p2119 reading on a code reader for my 2007 hyundai sonata. Please help


The throttle position sensor (TPS) is at fault. It is located on the side of the throttle body and is on a line with the throttle plate lever on the opposite side to the accelerator lever. Try pulling the electrical connector off and pushing it on a few times and see if that sorts things out. If not you will need to replace it. To clear the codes from the computer memory try disconnecting the battery for five minutes.

I have a 98 Hyundai accent. Won't accelerate over 50mph


the o2 sensor will cause overfuelling and an improper throttle position.
the heater circuit has 12v,and the other 2 wires are a reference voltage.
you need to use a scanner and look at the live data to see what the 02 sensor is doing.
after battery disconnect,the monitors have to set using a drive cycle of which you can get from hyundai.Typically to set the 02 heater circuit,the car has to idle for 2 minutes when cold,and then drive at 55mph for 3 minutes with the a/c on.

Get ready to replace the TPS (throttle position sensor).

TPS will act up is it wet or

one of more wire(s) are ground to the frame/engine.

Disconnect,clean and reconnect the TPS sensor.
Disconnect the battery for 4 minutes then reconnect.
Let the computer ECU re-learn the value of the resistance reading.


Is you throttle tension OK when it happen.

Lose throttle cable can also cause the same problem.

2002 throttle position sensor


The sensor is on the side of the throttle body, it has three wires going to it, it is connected to the throttle blade so when the throttle is opened it reads that info and sends it to the PCM.
