SOURCE: Car will not Idle

The TPS must be set with a voltage meter. What are the code numbers? Air flow meter will not let it idle too. Get a used one to save you money. Be sure you do not have the ecm number 1228253 in it also,they will make the car shut off while driving. I have one of the cars with 295,000 miles on it.

SOURCE: changed the TPS on my 05 sedona and it reads P0122

this code may cause by:

TPS not mounted securely.

TPS circuit short to ground or another wire.

Faulty TPS.

Damaged computer (PCM).

to fix this code you can try this:


Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.

A THROTTLE POSITION SENSOR (TPS) is usually located on the butterfly spindle so that it can directly monitor the position of the throttle valve butterfly.
Throttle actuator control(TAC), that code comes from that part of the system too.

SOURCE: Engine Hot A/C off - TPS?

Is not enough to reset the code, you have to replace the bed sensor.
When you buy a new one, they will let you know, where can you find it on the car.

2007 Suzuki XL7 - Error code reads p0122 and the computer in the dash reads Engine Hot- A/C off. It turned over earlier but Car wont start now. Battery is new, all fluid levels ok. AND... can anyone tell...


id use no start rules, the TPS 122 may be wrong. (idle switch)
ever use a cheap scan tool?
did you remove the TPS or fiddle its screws?
yes it does have calibration, and is different for each generation of car.
use alldata dot com or mitchells online, its all there.
or get a ebay fsm for this exact car cheap and used.

no starts:
flooding or dry sparks?
besides the basics, 1: good compresion and good timing)?
do you have spark. at 4 spark plugs.?
are the sparks dry or fuel soaked ?
if no spark , trouble shoot that.
if no fuel at all, check fuel pressure.
if flooding, a long list. of checks.
if it fails to start due to loss of fuel , try test fuel.

95 mercury i replaced tps and mass flow air and car running for 10 min now wont start at all


I would check for trouble codes in the computer and fuel pressure next.
You need to figure out if you are dealing with a no spark or low fuel pressure issue to proceed.

Changed the TPS on my 05 sedona and it reads P0122 code on scanner, after clearing the codes the check engine light wont turn off and the codes still reads P0122, maybe a bad TPS ?

96 nissan quest code p0120 p1705 the O/D flushes after startup. TPS was replaced but code still exists. Rough idle, loss of power and fuel economy.


this is an obd2 trouble code table, it can help you understand the meaning of code.
and for p0120
the Causes:
Sticking throttle return spring
MAP or TPS connector corrosion
Misrouted harness causing chafing
Bad TPS
Bad PCM
Possible Solutions:
If you have access to a scan tool, with KOEO (Key on engine off) observe the TPS voltage. With throttle closed, voltage should be about .45 volts. It should gradually sweep upwards to approximately 4.5 to 5 volts as you depress the throttle. Sometimes only a scope can capture an intermittent glitch in the TPS signal voltage. If you notice a glitch in the TPS sweep voltage, replace the TPS.
NOTE: Some TPS sensors require fine adjustment. If you aren't comfortable with using a DVOM (Digital Volt Ohm meter) to adjust the new TPS, then it's best to take the vehicle to a shop. If the voltage is not .45 volts (+or- .3 volts or so) with the throttle closed or if the reading is "stuck" then unplug the TPS connector. With KOEO check for 5 volts reference voltage present at the connector and a good ground. You can check the signal circuit for continuity by jumping a fused wire between the ground circuit of the TPS connector and the signal circuit. If the TPS reading on the scan tool now reads zero, then replace the TPS. However if that doesn't change the reading to zero, then check for an open or a short on the signal wire and if none is found, suspect a bad PCM. If manipulating the TPS wiring harness causes any change in idle, then suspect bad TPS.

Code 22 on 95 gmc sierra what does that mean also t will start up but wants to die we replaced idle air control valve and also the throttle position sensor did not fix it i check vaccum lines all good it...


Trouble Code 22 indicates that the Throttle Position Sensor (TPS) is reading abnormally low. TPS volts should be close to 0.42 V at closed throttle and rise smoothly in about 0.02 volt increments to a maximum reading of about 4.85 volts at WOT.
Typical causes for this code include:

1) Maladjusted TPS
2) Defective TPS
3) No +5 volt reference to TPS
4) TPS-return to ECM is shorted to ground or to sensor ground
5) Defective ECM

Good luck, i hope this helps.

My buick regal 2003 wont excelerate it starts


It may be the throttle position sensor. You should have a check engine light on in your dash. You will need to have someone plug a OBD II reader in and retrieve the code.
You can spend a LOT of money just putting in one part after another.
Please let me know what you find.
