Code P1286 Chrysler Description
The P1286 Chrysler diagnostic trouble code indicates that the Accelerator Position Sensor Supply Voltage is too high. The Accelerator Position Sensor (APS) is a crucial component of the vehicle's electronic throttle control system. It is responsible for sending a signal to the Engine Control Module (ECM) regarding the position of the accelerator pedal. The ECM uses this information to determine the appropriate fuel delivery and ignition timing for optimal engine performance.
Common Causes of P1286 Chrysler
- Faulty Accelerator Position Sensor
- Wiring issues or shorts in the APS circuit
- Malfunctioning Engine Control Module
- Electrical system problems
- Corrosion or poor connections in the sensor circuit
Symptoms of P1286 Chrysler
- Reduced engine power
- Poor acceleration
- Rough idling
- Engine stalling
- Limp mode activation
How to Fix P1286 Chrysler
- Diagnose the issue using a scan tool to confirm the P1286 code and identify the root cause.
- Inspect the APS and wiring harness for any visible damage or corrosion.
- Test the APS using a multimeter to check for proper voltage and resistance readings.
- Replace the Accelerator Position Sensor if it is found to be faulty.
- Clear the fault code from the ECM and perform a test drive to ensure the issue has been resolved.
Cost to Fix P1286 Chrysler
The typical repair costs for addressing a P1286 Chrysler code can vary depending on the specific cause of the issue. In general, replacing the Accelerator Position Sensor can cost anywhere from $150 to $300, including parts and labor. However, additional diagnostic time and potential ECM replacement can increase the overall repair costs. It is advisable to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on the specific circumstances of your vehicle. Keep in mind that labor rates can vary significantly based on location and the type of repair facility.

Frequently Asked Questions about P1286 Chrysler Code
1. What does the OBDII code P1286 mean on a Chrysler vehicle?
P1286 indicates that the supply voltage to the Accelerator Position Sensor (APS) is too high, which may interfere with proper throttle operation.
2. What are the common symptoms of the P1286 code?
Symptoms may include reduced engine performance, erratic throttle response, difficulty accelerating, or the vehicle going into limp mode.
3. What causes the P1286 code to appear in a Chrysler?
The code can be triggered by issues such as a faulty Accelerator Position Sensor, damaged wiring or connectors, or a malfunction in the Powertrain Control Module (PCM).
4. Can I drive my Chrysler with the P1286 code active?
Driving with this code is not recommended as it may lead to unpredictable throttle behavior and reduced safety.
5. How do I diagnose the P1286 code in a Chrysler?
Start by inspecting the Accelerator Position Sensor, wiring, and connectors for damage. Then, use a multimeter to check the sensor's voltage supply and signal.
6. Is the Accelerator Position Sensor the only part that can cause the P1286 code?
No, other potential causes include wiring issues, corroded connectors, or a failing PCM.
7. How can I fix the P1286 code on my Chrysler?
Repairs may involve replacing the Accelerator Position Sensor, repairing or replacing damaged wiring, or reprogramming or replacing the PCM if needed.
8. How much does it cost to fix a P1286 code on a Chrysler?
Costs vary depending on the issue, but replacing the Accelerator Position Sensor typically costs $100–$300, including parts and labor.
9. Can a dirty throttle body cause the P1286 code?
A dirty throttle body is unlikely to cause this specific code, but it's worth cleaning as part of routine maintenance when addressing throttle-related issues.
10. Will clearing the P1286 code with a scan tool fix the problem?
Clearing the code will reset the Check Engine Light, but the underlying issue must be resolved to prevent the code from returning.
