Discover the Importance of the 2007 Jeep Liberty Steering Angle Sensor: All You Need to Know
In the vast realm of automotive mysteries, few challenges are as vexing as unexpected warning lights and enigmatic sensor malfunctions. Picture this: cruising down the open road in your trusty 2007 Jeep Liberty, when suddenly, a symphony of illuminated icons demanding attention captures your gaze.
ESP/BAS lights and skidding icon lights flicker to life, leaving you puzzled and concerned. As you delve into the depths of the issue, one culprit emerges – the elusive steering angle sensor.
Join us on a journey of frustration and determination as we navigate the labyrinthine trials of replacing a malfunctioning 2007 Jeep Liberty steering angle sensor, in a quest to restore harmony to the open road.
2007 jeep liberty steering angle sensor
The 2007 Jeep Liberty steering angle sensor is a component that needs to be calibrated when the ABS system or battery is disconnected. The calibration process involves starting the engine, centering the steering wheel, and turning it all the way to the left and right before returning it to center.
If there is a fault in the steering angle sensor, it may require the removal or replacement of the steering wheel. In some cases, issues with the sensor can cause various lights to appear on the dashboard, such as the ESP/BAS lights and skidding icon lights.
The author experienced similar issues with their Jeep Liberty and suspected the speed sensors were the problem. They purchased four new sensors but encountered difficulties with the front ones when trying to remove them.
Ultimately, they found that the rear left sensor was faulty and replaced it. However, the lights reappeared after reversing.
The author also experienced brake activation when accelerating in first gear. Upon checking the front sensors, they found them to be in good condition.
Diagnostic trouble codes showed issues with the left rear wheel speed sensor, steering control module, steering angle sensor, and torque request signal denial. Finding the correct part number for the replacement steering angle sensor proved challenging, and the part was not currently available from Moparamerica.
The author considered purchasing a second-hand airbag/clock spring steering module from the UK. It’s important to note that the Jeep Liberty in question is a 2.8CRD Limited 6sp Manual model bought in 2007 but built in 2006.
Key Points:
- The 2007 Jeep Liberty steering angle sensor needs to be calibrated when the ABS system or battery is disconnected.
- Faulty steering angle sensor may require removal or replacement of the steering wheel.
- Issues with the sensor can cause various lights to appear on the dashboard.
- The author suspected speed sensors were the problem and purchased new ones, but had difficulties removing the front ones.
- Faulty rear left sensor was replaced, but lights reappeared after reversing.
- Diagnostic trouble codes showed issues with left rear wheel speed sensor, steering control module, steering angle sensor, and torque request signal denial.

💡 Pro Tips:
1. When calibrating the Steering Angle Sensor (SAS), make sure to follow the specific instructions in the service manual for your 2007 Jeep Liberty model.
2. If you suspect a faulty steering angle sensor, it may be necessary to remove or replace the steering wheel to access it properly.
3. If the ESP/BAS lights and skidding icon lights have been on since last year, it is worth checking the speed sensors and replacing them if necessary.
4. Be cautious when removing the front wheel sensors, as they may break during the process. If this happens, drill them out carefully and apply silicone grease when installing the new ones.
5. In case you’re having difficulty finding the correct part number for the replacement steering angle sensor, consider looking for a second-hand airbag/clock spring steering module from a reputable source, such as the UK.
Calibration Process For The Steering Angle Sensor (SAS)
The steering angle sensor (SAS) in a 2007 Jeep Liberty plays a vital role in the vehicle’s stability control system. It helps determine the angle at which the steering wheel is turned, allowing the system to make necessary adjustments for optimal vehicle performance.
However, whenever the ABS component or battery is disconnected, the SAS needs to be recalibrated to ensure accurate readings.
The calibration process involves the following steps:
This calibration process allows the SAS to establish its reference or zero point, which is crucial for accurate steering angle detection. It is important to follow this procedure carefully to ensure the SAS is calibrated correctly.
Clearing Codes In All Modules
In the event of an issue with the steering angle sensor or any other component in the vehicle’s system, it may be necessary to clear the codes stored in all modules. This process can be done by following the service manual instructions provided by the manufacturer.
To clear all codes in all modules, the following steps are typically recommended:
Clearing the codes in all modules helps reset the system and eliminate any stored fault codes that may be causing issues with the vehicle’s performance.
Removal Or Replacement Of Faulty Steering Angle Sensor
In some cases, the SAS in a 2007 Jeep Liberty may become faulty and require either removal or replacement. If the SAS is determined to be the root cause of the issues, it may be necessary to remove the steering wheel in order to access and replace the faulty sensor.
It is important to follow proper procedures and guidelines when removing or replacing the steering angle sensor to avoid any damage to the vehicle’s components. This task may require specialized tools and knowledge, so it is recommended to seek assistance from a professional if you are not confident in your abilities.
ESP/BAS Lights And Skidding Icon Issues On Jeep Liberty
One common issue that Jeep Liberty owners may encounter is the illumination of the ESP/BAS lights and the skidding icon on the dashboard. These lights serve as warning indicators and typically indicate a problem with the vehicle’s stability control system.
In the case of the author’s 2007 Jeep Liberty, these lights have been a constant issue since last year. Various troubleshooting steps were taken, including the suspected replacement of speed sensors.
It was found that the rear wheel sensors were functioning correctly, but the front ones broke when attempting to remove them. Drilling them out and applying silicone grease was attempted as a temporary fix.
However, further investigation revealed that the rear left sensor was actually faulty. Once it was replaced, the lights temporarily disappeared.
Unfortunately, they reappeared after reversing the vehicle. This indicated that there may be additional underlying issues contributing to the recurring problem.
Troubleshooting And Replacing Speed Sensors
As mentioned earlier, the author initially suspected that the speed sensors were responsible for the ESP/BAS lights and skidding icon issues. In an attempt to resolve the problem, four new speed sensors were purchased.
However, it was discovered that the front sensors were in good condition, while the rear left sensor was faulty.
Replacing the speed sensors, especially the rear left one, can be a challenging task. It is crucial to ensure proper installation and connection to avoid any further issues.
If you are unfamiliar with the process, it is advisable to seek professional assistance to ensure the job is done correctly.
In the case of the author’s Jeep Liberty, the rear left speed sensor was successfully replaced; however, the lights reappeared after reversing. This suggests that there may be additional underlying problems that need to be addressed.
Difficulty In Finding Correct Replacement Part For Steering Angle Sensor
When dealing with a faulty steering angle sensor, obtaining the correct replacement part is crucial. Unfortunately, the author of this article encountered difficulties in finding the correct part number for their 2007 Jeep Liberty.
The steering angle sensor is not currently available from Mopar America, which further adds to the challenge of obtaining a suitable replacement. As an alternative, the author considered purchasing a second-hand airbag/clock spring steering module from the UK to address the issue.
Finding the correct replacement part for a specific vehicle model can be a frustrating process. It is recommended to consult with experts or explore reputable online sources to ensure the right part is identified and acquired.
