The most common reasons a 2000 Toyota Celica cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2000 Toyota Celica cruise control isn't working?

Common Repairs

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.

If the cruise control refuses to turn on at all, the actuator could be at fault. Likewise, if the cruise control stays on but does not maintain a consistent speed, the problem could be a bad actuator. In extreme cases, a malfunctioning actuator could cause the throttle to stick and prevent the vehicle from slowing down. These symptoms may point to a bad actuator. They may also point to other problems with the cruise control and related systems.

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.

What are the initial steps to diagnose the non-functioning cruise control in a 2000 Toyota Celica?

When diagnosing the non-functioning cruise control in a 2000 Toyota Celica, it's crucial to adopt a systematic diagnostic approach. 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 wiring for any visible damage or loose connections, since faulty wiring can significantly hinder the system's operation. After ensuring the wiring is intact, test the cruise control switch itself; a malfunctioning switch is a common culprit behind cruise control failures. Additionally, examine the vacuum lines for any leaks or blockages, as these can directly impact the cruise control's performance. Finally, if the problem persists, utilize a diagnostic scanner to check for error codes that may provide further insight into the underlying issues. By following this structured approach, you can effectively diagnose and address the cruise control problems in your Toyota Celica, ensuring a smoother driving experience.

What are the common problems that could cause the cruise control to stop working in a 2000 Toyota Celica?

When troubleshooting the cruise control system in a 2000 Toyota Celica, it's essential to understand the common problems that may lead to its malfunction. One frequent issue is a faulty cruise control switch, which can hinder the system's ability to engage or disengage properly. Additionally, a blown fuse can disrupt the electrical flow necessary for the cruise control to function, while vacuum leaks can prevent the system from maintaining a consistent speed. Another critical component is the speed sensor; if it is defective, it can provide inaccurate speed readings, ultimately affecting the cruise control's performance. Furthermore, issues with the brake light switch can inhibit the activation of the cruise control, as the system relies on this switch to determine when to disengage. Lastly, a malfunctioning throttle cable can interfere with the system's ability to adjust the vehicle's speed effectively. By identifying these potential issues, DIY enthusiasts can better diagnose and address the problems affecting their cruise control system.

How urgent is it to repair the non-functioning cruise control in a 2000 Toyota Celica?

When evaluating the urgency of repairing the non-functioning cruise control in a 2000 Toyota Celica, it is crucial to recognize the potential safety risks associated with a malfunctioning system. A faulty cruise control can lead to unexpected acceleration or deceleration, which not only endangers the driver but also poses a threat to other road users. Additionally, the convenience factor cannot be overlooked; without cruise control, drivers may find themselves constantly adjusting their speed, leading to fatigue during long drives. Furthermore, a malfunctioning cruise control may signal deeper issues within the vehicle's electronic or engine control systems, which, if left unaddressed, could result in more significant performance problems. Therefore, it is advisable to prioritize the repair of the cruise control system to ensure a safer, more comfortable driving experience and to maintain the overall health of the vehicle.
