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.
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.

When troubleshooting the non-functional cruise control in your 1993 Chevrolet K1500 Suburban, start with a systematic diagnostic approach to identify the issue efficiently. Begin by inspecting the cruise control connector; disconnect it and look for any signs of damage or corrosion that could impede functionality. Next, enlist the help of a friend to operate the cruise control buttons while you observe the system's response, as this can reveal whether the issue lies within the controls or the system itself. If no response is noted, utilizing a scanner or diagnostic tool can provide deeper insights into potential error codes or malfunctions. Additionally, consulting a troubleshooting table specific to your vehicle can help pinpoint common issues and guide you toward the appropriate solutions. By following these steps, you can effectively narrow down the cause of the cruise control malfunction and take the necessary actions to restore its functionality.
When troubleshooting the cruise control system in a 1993 Chevrolet K1500 Suburban, it's essential to consider several common problems that may be at play. A failed control module is often a primary suspect, as it manages the cruise control functions. Additionally, issues with sensors or switches, such as a malfunctioning throttle position sensor, can disrupt the system's operation. It's also important to check the brake and clutch switches, as a failure here can prevent the cruise control from engaging. Wiring problems, particularly those caused by wear and tear from the tilt steering wheel, can lead to pinched or broken wires, further complicating the issue. Lastly, a blown fuse or a defective brake pedal switch can also be culprits. By systematically examining these components, DIYers can identify the root cause of the cruise control malfunction and take the necessary steps to restore functionality.
When evaluating the urgency of repairing the non-functioning cruise control on a 1993 Chevrolet K1500 Suburban, it is essential to recognize the potential safety risks associated with a malfunctioning system. A faulty cruise control can lead to unexpected acceleration or deceleration, which may compromise the driver's control over the vehicle, especially in high-traffic situations. Additionally, the absence of cruise control can significantly detract from the comfort of long drives, as the driver must continuously manage speed, leading to increased fatigue. Furthermore, a properly functioning cruise control system can enhance fuel efficiency by maintaining a steady speed, which is often more economical than fluctuating speeds caused by manual adjustments. Therefore, while the vehicle may still operate without immediate repairs, addressing the cruise control issue promptly is advisable to ensure a safer, more comfortable driving experience and to potentially reduce fuel expenses in the long run.
