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.
To diagnose the non-functioning cruise control in a 1992 Dodge Monaco, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the cruise control module, sensor, and throttle, as these components are often the root of the problem. Next, ensure that the cruise control is deactivated by gently pressing the brake pedal, which can sometimes reset the system. Pay close attention to the speed sensor wiring for any visible damage, as this can disrupt the cruise control's functionality. If the cruise control on/off button appears to be unresponsive, a gentle tap on the back of the steering wheel module may restore its operation. Additionally, check if the cruise control indicator light activates; if it does, you can bypass checking the Clock Spring, which is crucial for maintaining electrical connections while steering. Common culprits such as a blown fuse, malfunctioning brake light, or a defective brake switch should also be examined, as these can prevent the cruise control from engaging. Finally, inspect the transmission area, particularly the vehicle speed sensor (VSS) and its wiring. Testing the VSS by detaching it and manually spinning the shaft can confirm whether the speedometer responds, indicating whether the sensor is functioning correctly. By following these steps, you can effectively diagnose and potentially resolve the cruise control issues in your Dodge Monaco.
Addressing the non-functioning cruise control in your 1992 Dodge Monaco is crucial for both safety and driving comfort. When cruise control fails, it can lead to increased driver fatigue, especially on long trips where maintaining a consistent speed is essential. Moreover, the malfunction may signal deeper issues within the vehicle, such as problems with the cruise control switch, brake light switch, or even electrical components. Ignoring these symptoms not only compromises your driving experience but could also pose significant safety risks, particularly if the failure is linked to critical systems like the brake pedal or throttle. Therefore, it is imperative to diagnose and repair any cruise control issues promptly, as neglecting them could lead to more severe complications and potentially hazardous driving conditions. Prioritizing this repair will enhance your vehicle's performance and ensure a safer journey on the road.

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. 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.
