The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
When the throttle position sensor fails, the engine's computer tends to overcompensate with fuel, leading black exhaust coming from the tailpipe. There is a strong possibility of engine misfires, and the check engine light will come on.
Throttle position sensors can also develop "dead spots," or certain places along the throttle curve where it doesn't get a reading. When this happens, the above symptoms can occur but then stop when you further press or let off the gas pedal.
In the event that a wheel speed sensor fails, the ABS, traction control system (TCS) and manufacturer specific stability control system lights will illuminate, informing the driver that the systems are disabled. The vehicle will be more prone to tire slip, and normal driving patterns may need to be adjusted to correct for the loss of computer control. On older vehicle's, the speedometer can be affected, causing illumination of the check engine light as well.
The cruise control switch can cause complete failure of the cruise control feature, but in a lucky scenario only partial functionality will be lost. This means that the cruise control may come on, but that it will not increase in speed automatically, or the cancel button does not work leading the driver to cancel cruise control with the foot brake. In some vehicles, the cruise control light may illuminate, or a warning message may be displayed due to lack of functionality.
A faulty cruise control module will simply result in deactivation of cruise control settings. This is because a detected error in the cruise control system could lead to hazardous driving conditions, so the module will be disabled, and the cruise control system warning light will be displayed. This will be a different message depending on make and model, and a warning light or message may be displayed on the driver instrument cluster.
To effectively diagnose the non-functioning cruise control on your 2001 Saturn SW2, start with the simplest solutions before moving on to more complex issues. Begin by checking the fuse box for any blown fuses related to the cruise control system, as this is a common and easily fixable problem that can disrupt power to essential components. Next, inspect the brake lights, since they are often connected to the cruise control circuit; a malfunctioning brake light can prevent the system from engaging properly. After confirming the lights are operational, examine the cruise control cable adjuster to ensure it is correctly positioned, as improper adjustment can lead to driveability issues. Additionally, be mindful of the clutch engagement; riding the clutch can interfere with cruise control functionality, so ensure it is fully engaged when attempting to use the system. Finally, if the cruise control was previously disabled, try resetting it by pressing the RES/ACCEL button to return to the original set speed. By following this diagnostic approach, you can systematically identify and resolve the issue with your cruise control.
Repairing the non-functioning cruise control in a 2001 Saturn SW2 is not just a matter of convenience; it is a critical safety concern that should be addressed promptly. A malfunctioning cruise control system can lead to erratic vehicle behavior, affecting acceleration and speedometer accuracy, which can compromise your control over the vehicle. This is particularly concerning during long drives, where reliance on cruise control can reduce driver fatigue and enhance comfort. Ignoring these symptoms can escalate into more significant issues, potentially leading to costly repairs or even dangerous driving situations. Therefore, it is essential to prioritize the repair of your cruise control system to maintain the overall functionality and reliability of your vehicle, ensuring a safer and more enjoyable driving experience.
