P0489 Chrysler Code - Exhaust Gas Recirculation Throttle Control Circuit 'A' Circuit Low
Quick Answer
The P0489 Chrysler code indicates a problem with the Exhaust Gas Recirculation (EGR) Throttle Control Circuit 'A', specifically a low voltage condition. Common causes include Faulty EGR Valve: A malfunctioning EGR valve can cause issues with the throttle control circuit, Wiring or Connector Issues: Damaged wiring or poor connections in the EGR throttle control circuit can lead to a low voltage condition, ECU Malfunction: A problem with the Engine Control Unit (ECU) may prevent proper communication with the EGR system. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0489 Chrysler Description
The P0489 Chrysler code indicates a problem with the Exhaust Gas Recirculation (EGR) Throttle Control Circuit 'A', specifically a low voltage condition. The EGR system helps reduce emissions by recirculating a portion of the engine's exhaust gases back into the intake system to be re-burned. The throttle control circuit is responsible for regulating the amount of exhaust gas flowing through the EGR system. When this circuit operates at a lower voltage than expected, it can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
Common Causes of P0489 Chrysler
- Faulty EGR Valve: A malfunctioning EGR valve can cause issues with the throttle control circuit.
- Wiring or Connector Issues: Damaged wiring or poor connections in the EGR throttle control circuit can lead to a low voltage condition.
- ECU Malfunction: A problem with the Engine Control Unit (ECU) may prevent proper communication with the EGR system.
- Carbon Build-up: Accumulation of carbon deposits in the EGR system can restrict flow and affect circuit performance.
- Vacuum Leaks: Any leaks in the vacuum lines connected to the EGR system can disrupt the proper operation of the throttle control circuit.
Symptoms of P0489 Chrysler
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Rough Idle: A decrease in engine performance, such as rough idling or stalling, may occur due to improper EGR function.
- Reduced Power: The vehicle may experience a loss of power or acceleration due to inefficient exhaust gas recirculation.
- Increased Emissions: A malfunctioning EGR system can result in higher emissions output, potentially causing the vehicle to fail emissions tests.
- Poor Fuel Economy: The engine may consume more fuel than usual if the EGR system is not functioning properly, leading to decreased fuel efficiency.
How to Fix P0489 Chrysler
- Diagnostic Scan: Use a diagnostic scanner to retrieve the specific trouble codes and pinpoint the issue with the EGR throttle control circuit.
- Inspect EGR System: Check the EGR valve, wiring, and connectors for any damage or faults that may be causing the low voltage condition.
- Clean or Replace EGR Valve: Clean the EGR valve to remove carbon deposits, or replace it if it is faulty and beyond repair.
- Repair Wiring or Connections: Address any wiring issues or repair/replace damaged connectors in the EGR throttle control circuit.
- Reset ECU: After completing repairs, reset the ECU to clear the trouble codes and ensure the system is functioning properly.
Cost to Fix P0489 Chrysler
The cost of repairing the P0489 Chrysler code can vary depending on the specific cause of the issue and the labor rates of the repair shop. On average, the repair costs for this problem can range from $200 to $500, including parts and labor. It's important to note that additional diagnostic time may be needed to accurately diagnose the issue, and labor rates can fluctuate based on location and the type of repair facility. It's recommended to consult with a trusted mechanic or shop for a more precise cost estimate.
