Issue with throttle position sensor and Check Engine light is on.
The Check Engine lights is on and the power locks do not respond to remotes. The throttle position sensor has come on, however, it goes off after restarting the car.
Experienced mechanics share their insights in answering this question :
I’m not quite sure what to make of this description, but I’m guessing you are trying to say the check engine light goes off and on intermittently with a code stored for the throttle position sensor (TPS). I do not have the wiring diagram for this vehicle handy, but I doubt the problems with the TPS has anything to do with the inoperative remotes. The TPS and its corresponding circuit will need to be diagnosed for faults. Then the power lock issue will have to be addressed separately. The door lock module, or anti-theft module, may simply need to be reprogrammed to recognize your keys. A trained technician, such as the ones at YourMechanic, will be able to help you diagnose both issues.

Illuminated Check Engine Light
If your car has a loose TPS connector (wire) or the throttle sensor fails to monitor throttle functioning properly, it will affect the engine performance, and the engine will trigger the Check Engine Light in response.
Common signs include lacking power when accelerating, rough or slow idle, stalling, inability to shift up, and the Check Engine Light coming on.
A malfunctioning TPS will cause your engine to run poorly. Generally the engine will idle fine but will have difficulty accelerating. This is because the computer isn`t telling the engine to inject as much fuel as is required, while at the same time airflow is increasing.
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Faulty throttle and pedal position sensor
Any problem within the TAC system can cause the reduced engine power warning light to go on. One of the more common reasons includes one or both APP sensors in the accelerator pedal or the pair of TP sensors.
Accelerator Pedal Release Position Learning Procedure.
Make sure that the accelerator pedal is fully released. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds.
a faulty tps can set a trouble code in the computer if the voltage value is either not present, sporadic, slow or constant, and this can illuminate your check engine light.
A P0122 code is the generic OBD-II code defined as “Throttle Pedal Position Sensor/Switch (TPS) A Circuit Low Input.” This code relates to the vehicle`s Engine Control Module (ECM) and TPS Sensor Circuit A output voltage and is triggered when the voltage falls below the sensor`s anticipated range.

Hi there. What you received from the parts store was a code retrieval, not a diagnostic. The codes are set when a fault is detected against normal operating parameter. The computer does not know what caused the fault, only that the fault meets the criteria for this code to set. There could be a problem in the wire harness, converter, or the ECM. The code and data are needed to properly assess the direction that a diagnosis needs. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a check engine light inspection.

It is possible that you could be having an issue with your powertrain control module. This is somewhat of a common problem on many GM vehicles. I would recommend having your vehicle inspected by the dealership to determine if the powertrain control module is functioning properly. If not, a reflash of the powertrain control module may resolve the issue but often times it must be replaced.
O2 sensors changed, but check engine light still showing code after clearing it I checked fuse. Wires are good and used Denso OE.
Depending on what the code was for will determine if the oxygen sensor was to be replaced. If the conditions were for a rich or lean mixture and it said oxygen sensor, then the spark plugs and wires could need replaced if its a rich reading or the fuel injectors could be clogged or not working if its a lean mixture. If the code said that the oxygen sensor was bad, then check the harness and see if there is a break in the wiring or a short to ground in the wiring from the oxygen sensor to the main harness. If you need further assistance with your check engine light being on, then seek out a professional, such as one from Your Mechanic, to help you.

This may happen for a couple of reasons. First, check to be sure that the connections to the sensor are clean and not faulty or broken. Secondly, check to be sure you replaced the correct sensor as there are two camshaft position sensors in some applications.

Check engine light refuses to go off after engine replaced
Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.
Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.
To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.
Kia Sporate Engine check light issue and car stalled this morning!
The infamous "loose gas cap code" is P0442. P0434 is an issue with a heated catalytic converter not coming up to temperature quickly enough. It can be caused by the fuel injection being too rich. If you starter is not turning your engine over, the issue could be a dead battery.
If you can get it jumped off, most auto parts stores will check the battery for free. They will also, time permitting, check your engine codes for free. This will help guide diagnosis for whatever else is still wrong with your vehicle.
If you need assistance with the repairs from here, I would recommend having your Check Engine Light inspected by a certified technician, like one from YourMechanic, to diagnose the problem, get an accurate assessment of damage and cost estimate for repairs. YourMechanic can dispatch a mobile, professional mechanic to your location for this repair.
Traction light/reduced engine power and check engine light coming on
Hello. From what you describe, it would appear that your vehicle may be experiencing some sort of intermittent wiring or sensor issue. If the problem occurred again after driving over a bump, then it may be possible that a damaged or loose wire is shorting or having contact issues. A common issue that can cause stalling is a faulty crank position sensor or wiring. I would carefully examine the engine for any loose or damaged wires. If the Check Engine Light comes back on, I would recommend having the trouble codes scanned before resetting the computer.
