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.
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.
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.
When diagnosing the non-functioning cruise control in a 1997 Oldsmobile Bravada, it's essential to adopt a systematic diagnostic approach that prioritizes simpler checks before delving into more complex issues. Start by examining the control module, sensor, and switch, as these components are often the culprits behind cruise control failures. Next, inspect the throttle actuation system to ensure it is functioning correctly, as any malfunctions here can directly impact cruise control performance. Additionally, the vacuum actuator plays a crucial role in the system, so checking its operation is vital. Don't overlook the vacuum hoses; any damage or leaks can significantly affect the system's functionality. Finally, assess the cable that connects the actuator to other components for any signs of wear or damage. By following this methodical approach, you can effectively identify and address the underlying issues affecting your vehicle's cruise control system.
When dealing with a non-functional cruise control system in a 1997 Oldsmobile Bravada, it's essential to consider several common problems that could be at play. One of the first areas to check is the cruise control switch, as a faulty switch can prevent the system from engaging or disengaging properly. Additionally, a blown fuse may disrupt the electrical flow necessary for the cruise control to operate, so inspecting the fuses is a crucial step. Another potential issue could be vacuum leaks within the cruise control system, which can significantly affect its performance. The speed sensor also plays a vital role, as a defective sensor can hinder the system's ability to maintain a constant speed. Lastly, don't overlook the brake light switch; if it's malfunctioning, it may interfere with the cruise control's operation. By systematically examining these components, DIYers can identify and address the root cause of the cruise control failure, potentially saving time and money on repairs.
Addressing the non-functioning cruise control in a 1997 Oldsmobile Bravada is crucial for several reasons. First and foremost, safety is a primary concern; a malfunctioning cruise control system can lead to erratic speed changes, increasing the risk of accidents on the road. Additionally, the comfort and convenience that cruise control provides during long drives cannot be overlooked, as it significantly reduces driver fatigue. Furthermore, ignoring this issue may indicate deeper problems within the vehicle's electronic systems or engine, which could escalate into more severe and costly repairs if not addressed promptly. Therefore, it is essential to prioritize fixing the cruise control to ensure a safe and enjoyable driving experience while preventing potential future complications.
