Can a tire pressure monitor be installed on a GMC Sierra?
It doesn’t look like the trailer tire pressure monitor system can be retrofitted for units of the 2019 GMC Sierra that don’t come with the system from factory, as GMC states that the system “must be ordered with the vehicle and installed by the factory.” GMC states that additional or replacement sensors will be available as a GM Accessory.
What happens when the throttle moves on a GMC?
As the throttle moves, a voltage signal ranging from 0.5 volts to 5.0 volts is sent to the engine computer. If the sensor fails, the computer has no precise control over the engine fuel delivery.
Can You disable the TPMS in GM vehicles?
The U.S. Department of Transportation has mandated that all vehicles manufactured after 2008 include a tire pressure monitoring system (TPMS). Although you cannot disable the TPMS in a General Motors (GM) vehicle, you can reset the system if you recently checked your tires and inflated them properly.

How to do throttle body re-Learn Chevy Malibu?
1) Start the engine and let it idle in park for 3 minutes. During that period the idle may be higher idle than normal. 2) After 3 minutes, turn the engine off and leave it off for 60- seconds. 3) Start the engine again and let it idle in park for 3 minutes one more time. During these run periods you may see a check engine light.
What happens when the throttle pedal moves on a GMC?
When the throttle pedal moves, the throttle sensor also moves in direct response to the driver commands. As the throttle moves, a voltage signal ranging from 0.5 volts to 5.0 volts is sent to the engine computer.
How does a GM throttle body relearn procedure?
A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position. If the buildup occurs gradually, the PCM “learns” the new home position.

How long does it take for GM throttle body to relearn?
If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle. It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle. 1) Start the engine and let it idle in park for 3 minutes.
What happens when you replace the throttle body?
If you replace the throttle body, the PCM won’t know and will continue to use the adaptive settings as if the carbon buildup is still in place. If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle.
How does the throttle plate work on a GM car?
A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position.
How can I Reset my throttle position sensor?
Reprogramming or resetting your sensor can sometimes solve these issues. This step can also be necessary when you install a new sensor. 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.
Can a bad throttle position sensor cause stalling?
Similarly, if your engine struggles to idle efficiently, it could also be a result of a damaged throttle position sensor. Stalling, surging, or hesitating while idling all can be caused by this unassuming sensor. The best way to determine if these issues are caused by your throttle position sensor is to go to the source.

Why do you need a throttle position sensor?
Average rating from 93 customers who received a Throttle Position Sensor Replacement. The throttle position sensor (TPS) is part of your vehicle’s fuel management system and helps ensure that the correct mixture of air and fuel is delivered to your engine.
How do you unplug a throttle sensor?
Unplug the throttle sensor by lifting up the plug clip and pulling directly back on the connector. Unbolt the sensor using a socket to fit the small bolts. These are locked in with thread lock compound, so be careful to keep steady pressure and not strip the bolt heads.
What are the DTC codes for the throttle position sensor?
TPS diagnostic trouble codes (DTC’s) stored in the vehicle’s computer’s memory. P0121: Throttle Position Sensor Performance. P0122: Throttle Position Sensor Circuit Low Voltage. P0123: Throttle Position Sensor Circuit High Voltage. Really bad gas mileage. Transmission does not shift out of second gear.
What happens when the throttle position sensor fails?
Start the GMC and perform a test drive to make sure the system is operating correctly. When a throttle position sensor fails, the GMC runs, but fuel mileage and performance suffer because an important part of the data stream from the engine management system is interrupted.

What should I know before jumping the starter solenoid?
This is the most important thing to check before thinking about jumping the starter solenoid. You need to make sure that your car battery can supply enough current to start the solenoid and turn your engine. Even if your vehicle has a bad starter solenoid, you need a good and strong battery to start the engine.
Where is the starter motor located on a car?
But on some car models, the starter motor is located where the engine and the transmission should meet. The starter motor is a cylindrical metal component. The smaller cylindrical part affixed on top or on the side of the starter motor is the starter solenoid. Basically, if you found the starter motor, then you have found the starter solenoid.
