What happens when a bad throttle position sensor occurs?
The data provided by TPS is invaluable for proper starting, idling, and easy throttle response. These operations are affected when a bad throttle position sensor feeds erroneous data to the car’s computer. Because of this, the following can occur:
Can a car not tell if the throttle is fully shut?
Similar to getting jerks while accelerating, with a faulty TPS, the computer cannot tell if the throttle is fully shut when the car is idling. This can happen anytime, without any kind of warning, while driving or idling. The TPS can give a bad input, prompting the engine to stall. This is a particularly hazardous situation.
How do you test a non adjustable throttle?
In order to test a non-adjustable one, such as a potentiometer TPS, a voltmeter is used, like so: 1. Disconnect the throttle sensor harness. 2. Open the throttle valve manually and check the resistance changes between the terminal 1 and 2. 3. Check the resistance in three different positions of the accelerator pedal.
Is there a way to reset the throttle body?
This method is almost foolproof as long as all ECU control parameters are within their normal ranges. Resetting The Throttle Body Calibration (this step is conditional) A Rough Idle or a SES can sometimes be caused by a change in the throttle body position sensor calibration.
Why is the throttle body clicking on my Saturn Vue?
Also as far as the throttle body when they set throttle position codes without unplugging it you usually end up replacing the throttle body the harness to it and a harness mount that keeps the new harness you splice in from vibrating and breaking the wires inside the insulation. Thats common on Those and the saturn vues.
What’s the throttle body relearn procedure for a Saturn?
Start engine and ensure the engine speed is between 450 to 4,000 RPM. 2. Check that manifold absolute pressure (MAP) is greater than 5 kPa. 3. Check that the mass air flow (MAF) is reading is greater than 2 g/s. 4. Check that the ignition 1 voltage is greater than 10 volts. 5. Idle the engine in PARK for 3 minutes. 6.
Can a car start with a throttle body Unplugged?
Obviously with false throttle body codes but with throttle body unplugged, that is the only way the vehicle will start. While it is running you can plug it back in and will stay running but it still has almost no throttle response from pedal. Still diagnosing the problem but have already replaced throttle body and harness with no success.
What does it mean when throttle body does not connect?
The car will turn over. But I have no acceleration and after awhile the engine starts to shake. When the throttle body is connected the OBD meter will not connect, it says error. When disconnected the OBD meter works and says error codes P0123 and P0222.
