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.
When diagnosing the non-functioning cruise control in a 1991 Pontiac 6000, it's essential to adopt a methodical approach that starts with the most straightforward solutions. Begin by checking the fuse associated with the cruise control system, as a blown fuse is a common and easily fixable issue. Next, inspect the cruise control switch to ensure it is operational; a malfunctioning switch can prevent the system from engaging. Following this, examine the vacuum lines, which are crucial for the cruise control's functionality in older vehicles. Look for any signs of leaks or damage that could disrupt the vacuum pressure. If these initial checks do not resolve the issue, proceed to test the cruise control module, as it may be malfunctioning. Lastly, ensure that all connections related to the cruise control system are secure and free from corrosion, as loose connections can significantly impact performance. By following this structured diagnostic approach, you can effectively identify and address the root cause of the cruise control malfunction in your Pontiac 6000.
When dealing with a malfunctioning cruise control system in a 1991 Pontiac 6000, it's essential to understand the common problems that may be at play. One of the first things to check is the fuse associated with the cruise control; a blown fuse can easily disrupt the system's functionality. Next, inspect the cruise control switch itself, as a faulty switch may prevent the system from engaging or disengaging as intended. Additionally, vacuum leaks can significantly impact the operation of the cruise control, so examining the vacuum lines for any signs of wear or damage is crucial. The speed sensor also plays a vital role in maintaining a consistent speed, and if it's malfunctioning, the cruise control may not work correctly. Furthermore, issues with the brake light switch can interfere with the system's ability to engage or disengage, so ensure that this component is functioning properly. Lastly, check the throttle cable for any malfunctions, as this can affect the cruise control's ability to maintain speed. By systematically addressing these common issues, DIYers can effectively troubleshoot and potentially resolve the cruise control problems in their Pontiac 6000.
When assessing the urgency of repairing a malfunctioning cruise control system in a 1991 Pontiac 6000, it's essential to weigh the implications of the malfunction against the vehicle's overall safety and performance. While a faulty cruise control may not pose an immediate safety risk, issues such as blown fuses, malfunctioning brake lights, or a defective brake switch can lead to significant safety concerns that warrant prompt attention. Additionally, if the cruise control malfunction is accompanied by a check engine light or other engine-related problems, it becomes crucial to address these issues swiftly to prevent further damage and ensure optimal vehicle performance. Therefore, while the repair may not be classified as an emergency, timely intervention is advisable to maintain the vehicle's functionality and avoid potential complications down the road.

When the vehicle speed sensor fails or the wiring harness prevents signal transmission, the speedometer is the first thing that will stop functioning properly. This can be an intermittent issue where the speedometer only works occasionally, the speedometer may cease all function, or the speedometer may read erratically or incorrectly. Also, the traction control and anti lock brake warning lights specific to each vehicle may be illuminated, depending on the design of those systems. You may notice the vehicle hesitate to accelerate, cruise control will not function properly, and the vehicle may not shift properly through all of the gears.
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.
