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 troubleshooting cruise control issues in your Dodge Avenger, it's essential to adopt a systematic diagnostic approach. Begin by checking the cruise control switch, as this is often the simplest and most accessible component to inspect. If the switch appears faulty, replacing it could resolve the issue. Next, examine the control module, which plays a crucial role in the cruise control system's functionality; ensure it is operating correctly, as repairs or replacements may be necessary. Following this, inspect the throttle to confirm it is in good working condition, as any malfunctions here can directly impact cruise control performance. Additionally, sensor problems are common culprits, so check all relevant sensors for proper operation and replace any that are malfunctioning. If you notice that the cruise control fails to engage shortly after starting a cold engine, consider the engine temperature sensor, as a fault here can affect multiple systems. Lastly, if warning lights appear on your dashboard, reviewing diagnostic trouble codes (DTCs) can provide valuable insights into the underlying issues. By following this structured approach, you can effectively identify and address the cruise control problems in your Dodge Avenger, ensuring a smoother driving experience. If issues persist after these checks, seeking assistance from a certified mechanic is recommended for a thorough diagnosis.
When dealing with cruise control malfunctions in a Dodge Avenger, it's essential to consider several common problems that could be at play. One of the most frequent culprits is a blown fuse or a defective brake pedal switch, both of which can disrupt the electrical signals necessary for cruise control to function. Additionally, issues with the control module, sensors, or throttle can also impede the system's performance, leading to erratic behavior or complete failure. Another significant factor to investigate is the throttle position sensor; if it malfunctions, it can cause the engine's computer to mismanage fuel delivery, which may result in noticeable symptoms like black exhaust. By understanding these potential failure modes, DIYers can effectively troubleshoot and address the underlying issues affecting their vehicle's cruise control system.
When the cruise control in your Dodge Avenger stops functioning, it’s crucial to address the issue promptly to ensure your safety and the vehicle's performance. Common causes include a failed control module, faulty sensors, or malfunctioning switches, which can disrupt the system's operation. Additionally, a blown fuse or a defective brake pedal switch often leads to cruise control failure, as these components are integral to the system's functionality. Problems with the throttle control system or the anti-lock braking system (ABS) can also interfere with cruise control, making it essential to inspect these areas. Furthermore, physical damage, such as broken mounts for the circuit board that connects the cruise control button, can prevent proper operation. Ignoring these symptoms not only compromises your driving experience but could also lead to more significant issues down the line, making it vital to diagnose and resolve the problem as soon as possible.
