Throttle position sensor
A throttle position sensor (TPS) is a sensor used to monitor the throttle position of a car. The sensor is usually located on the butterfly spindle/shaft so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used, for example an extra closed throttle position sensor (CTPS) may be employed to indicate that the throttle is completely closed.

P1121 - Throttle Position (TP) Sensor Inconsistent with MAF Sensor The PCM monitors a vehicle operation rationality check by comparing sensed throttle position to mass air flow readings. If during key ON engine running self-test the comparison of the TP sensor and MAF sensor readings are not consistent with calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.

• Air leak between MAF sensor and throttle body
• TP sensor not seated properly
• Damaged TP sensor
• Damaged MAF sensor

Drive vehicle and exercise throttle and TP sensor in all gears. A TP PID (TP V PID) less than 4.82 % (0.24 volt) with a LOAD PID greater than 55% or a TP V PID greater than 49.05% (2.44 volts) with a LOAD PID less than 30% indicates a hard fault.

P0122 is TPS signal low, which could mean you have a bad TPS, or a fault in the wiring or connector. I suspect a bad Throttle Position Sensor.

Having Check Light On & getting a code, doesn't
mean your car needs anything

It means you use the code to direct you to a place
to start testing things.

Parts only get replaced, when they fail a test

You can throw some parts at it & get lucky a few times

What I don't like about that, is you learn nothing from doing
that.

The TPS Sensor (throttle position sensor) pretty much tells
you where it is. On the Throttle Body--- for the past 30 years,
not a well kept secret!

You should test it before replacing, just to make sure there isn't another problem you are missing. The computer only knows something isn't right.
I would do the testing before removal, as the tps is integrated with the throttle actuation motor. Remove the connector from the sensor and use an ohmmeter to check the sensor. Inspect the connector and pins carefully for damage. Also inspect the wires carefully. If visual inspection looks good, move on to testing. The sensor circuit includes three pins in the connector--pins B, D, and H in the lower left of the diagram below. Remove the rubber air pipe from the throttle so you can open the throttle by hand. Then connect your ohmmeter to pins H and D. Then slowly open the throttle by hand. The resistance between the pins should change continuously and linearly as you open the throttle by hand. If that test is good, move the ohmmeter probes to pins B and D and run the same test. If the sensor fails these tests, replace the whole integrated throttle control assembly. If it passes, the problem is probably with the connector or wiring.

Hi.

The problem is regarding TPS (throttle position sensor located in throttle body). Both codes are TPS voltage out of range (low and high) If you get both codes at once, then :

TPS may be defective,
wiring to TPS may be shorted to ground.
There may be a problem in the +5V circuit powering the TPS.
There may be a problem with ECU connector.

How to Replace a Throttle Position Sensor
(DIY & Save up to $135.75 ) - Time: 2.1 hours

Parts:
1. Throttle Position Sensor - $ 55.44

Tools:
1. Scan Tool
2. Screwdriver
3. Multimeter

Procedure:
1. Locate the OBD data link connector (DLC). Refer to your owner’s manual for the specific location.

• Tip: The OBD-I data link connector is usually located in the engine compartment near the battery or the fuse box. The OBD-II connector (post 1995 cars) is usually located beneath the instument panel next to the steering column.

2. Turn your key to the“ON” position. Do not start the engine.

3. Plug your scan tool into the OBD data link connector. Turn on the scan tool and select the appropriate steps to read the diagnostic trouble code (DTC).

Scanner plugged into OBD-II data link connector.

• Tip: The OBD-II diagnostic trouble code (DTC) is a 5 character alphanumeric code. The first digit is a letter that indicates the component group, the second digit is OBD mandated or manufacturer specfic, the third digit is a subgroup, and the fourth and fifth digits define the component and basic problem.
  

• 4. Locate the throttle position sensor.

• 
  
• Throttle position sensor
  

• 5. Disconnect the electrical connector from the throttle position sensor.

• 
  
• Electrical connector removed
  

6. Test the resistance of the throttle position sensor (TPS) with a digital multi-meter. If the resistance is out of specifications, the TPS must be replaced.

• 7. Remove the throttle position sensor.



Removing sensor mounting screws

8. Install the new throttle position sensor. Tighten the mounting screws and attach the electrical connector.

• 9. Erase the diagnostic trouble code (DTC) with the scan tool using the“delete” or“erase” command. Road test your vehicle to see if the check engine light returns.

Check engine light


• Tip: If the check engine light returns, repeat the diagnostic process for additional DTCs or take your vehicle to a certified repair shop.

Direct OE replacement

Hope helped with this. Good luck (remember rated this help).
