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 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.

When troubleshooting the non-functional cruise control in a 1996 Chevrolet Lumina APV, it's essential to adopt a systematic diagnostic approach that prioritizes simpler fixes before delving into more complex issues. Begin by checking the fuse associated with the cruise control system, as a blown fuse is a straightforward and common culprit that can easily be replaced. Next, inspect the wiring for any visible damage or loose connections, as faulty wiring can disrupt the system's functionality. Testing the cruise control switch is also crucial, as a malfunctioning switch can prevent the system from engaging. Given the age of the vehicle, it's important to check the vacuum lines for any leaks or damage, as these can significantly impact the operation of the cruise control. Utilizing a diagnostic scanner to check for error codes can provide valuable insights into specific issues affecting the system. Finally, inspect the cruise control module for signs of damage or corrosion, as a defective module can be the root cause of the problem. By following these steps in a logical order, you can effectively diagnose and potentially resolve the cruise control issue in your Lumina APV.
When diagnosing cruise control issues in a 1996 Chevrolet Lumina APV, it's essential to consider several common problems that may be at play. One frequent culprit is a failed control module or switch, which can prevent the system from engaging properly. Additionally, issues with the vacuum actuator can disrupt the functionality, as this component is crucial for maintaining the desired speed. Another area to inspect is the fuse related to the cruise control system; a blown fuse can easily interrupt the electrical flow necessary for operation. Lastly, a malfunctioning brake switch can also be a significant factor, as this switch is designed to deactivate the cruise control when the brakes are applied. By systematically checking these components, DIYers can effectively troubleshoot and potentially restore the cruise control functionality in their Lumina APV.
When evaluating the urgency of repairing the non-functioning cruise control in your 1996 Chevrolet Lumina APV, 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 your ability to maintain control of the vehicle, especially during long drives where fatigue is a factor. Additionally, the convenience of cruise control significantly enhances the driving experience, allowing for a more relaxed journey on highways and reducing the physical strain of constant speed regulation. Furthermore, neglecting this repair could adversely affect the resale value of your vehicle; prospective buyers often seek cars with fully operational features. Therefore, while the issue may not be as critical as a brake failure, addressing the cruise control malfunction promptly is advisable to ensure safety, enhance driving comfort, and preserve the vehicle's market appeal.
