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.
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.
To effectively diagnose the non-functional cruise control in your 1990 Plymouth Laser, start with a methodical approach that emphasizes simplicity and accessibility. Begin by checking the fuse associated with the cruise control system, as a blown fuse is a straightforward issue that can easily disrupt functionality. Next, inspect the vacuum lines for any signs of leaks or damage, since these are crucial for the system's operation. If the vacuum lines appear intact, proceed to test the cruise control switch to ensure it is working properly, as a faulty switch is a common culprit in cruise control failures. Additionally, examine the speed sensor, which plays a vital role in maintaining speed; a malfunction here can significantly affect cruise control performance. Finally, consider using a diagnostic scanner to check for any error codes that may provide insight into underlying issues. By following this structured diagnostic approach, you can efficiently identify and address the problems affecting your cruise control system, making your DIY repair process smoother and more effective.
When troubleshooting the cruise control system in a 1990 Plymouth Laser, it's essential to consider several common problems that could be affecting its functionality. One of the first things to check is the fuse associated with the cruise control; a blown fuse can completely disable the system. If the fuse is intact, the next step is to inspect the cruise control switch, as a malfunctioning switch may prevent the system from engaging or disengaging properly. Additionally, vacuum leaks can disrupt 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 faulty, the cruise control may not function as intended. Furthermore, issues with the brake light switch can interfere with the system's ability to engage or disengage, so ensuring that this component is working correctly is important. Lastly, a malfunctioning throttle cable can hinder the cruise control's performance, making it necessary to check for any obstructions or damage. By systematically addressing these potential issues, you can effectively diagnose and resolve the problems with your cruise control system.
While repairing the non-functioning cruise control in a 1990 Plymouth Laser may not seem urgent, it is wise to address the issue sooner rather than later. Cruise control enhances driving comfort, especially on long highway trips, and its absence can lead to fatigue and discomfort during extended drives. Although the malfunction does not compromise the vehicle's basic safety, neglecting the repair could result in more complex issues down the line, such as electrical problems or increased wear on other components. By troubleshooting and fixing the cruise control system promptly, you not only restore a valuable feature of your vehicle but also prevent potential inconveniences that could arise from prolonged neglect. Therefore, while it may not be an immediate safety concern, taking action to repair the cruise control will enhance your driving experience and maintain the overall health of your Plymouth Laser.
