What causes a flat spot on a TPS sensor?

What causes a flat spot on a TPS sensor?

Contact-style TPS sensors can develop a worn spot just above the idle position as the miles add up. This, in turn, may create a “flat spot” that results in momentary hesitation or stumble when the driver steps on the gas. This may not set a fault code because the glitch occurs too quickly for the OBD II system to detect.

When do you need to replace a TPMS sensor?

A TPMS sensor’s ability to generate a good signal can be checked with a special TPMS tester that energizes the sensor and listens for a radio signal back from the sensor. If a sensor has failed or is not reading accurately, it needs to be replaced. “Universal” aftermarket TPMS sensors are available for a wide variety of applications.

When does a throttle position sensor need to be replaced?

Throttle Position Sensors. The sensor’s out put can be checked with a voltmeter, or observed on a scan tool. If there are any drops in the output as the throttle opens, the sensor is bad and needs to be replaced. On some older vehicles, the idle voltage setting of the sensor must be adjusted to a specified voltage.

When to replace wheel speed sensors and why?

If the wiring is okay but the sensor is reading out of range, the sensor needs to be replaced. Note: On vehicles where the wheel speed sensor is an integral part of the hub and wheel bearing assembly, the entire hub must be replaced if the sensor is bad.

How is the throttle position sensor ( TPS ) used?

The throttle position sensor (TPS) is used to inform the powertrain control module (PCM) of throttle position. The PCM uses this information to determine control of various output devices, such as the fuel injectors, transmission shift solenoids, etc.

When to replace the TPS sensor on a Dodge Magnum?

If your truck experiences poor idle, terrible acceleration or worse gas mileage, then its time to replace that TPS sensor. For Dodge ‘Magnum’ engines 239 (3.9L) V6, 318 (5.2L) and 360 (5.9L) V8 from 1993 to 2003. Keep in mind that there are minor differences in the electrical connections, but the removal is the same.

The parts will cost you between $75 and $130 on average. The labor costs will be anywhere between $60 and $90, depending on the hourly rate of the mechanics.

What are the symptoms of a failed throttle position sensor?

Its internal resistance and output signal voltage change in relation to throttle position. Some common symptoms of a failed throttle position sensor include hesitation, poor acceleration, rough idle, increased emissions and an illuminated Check Engine Light.
