P0699 KIA Code - Sensor Reference Voltage 'C' Circuit High

Quick Answer

The P0699 code for KIA vehicles indicates an issue with the sensor reference voltage 'C' circuit being too high. Common causes include Faulty Sensor: A malfunctioning sensor that is receiving too much voltage can trigger a P0699 code, Wiring Issues: Damaged or corroded wiring connected to the sensor can cause voltage irregularities, Malfunctioning PCM: A problem with the powertrain control module that controls the sensor reference voltage can lead to this issue. 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 P0699 KIA Description

The P0699 code for KIA vehicles indicates an issue with the sensor reference voltage 'C' circuit being too high. In simpler terms, this means that the voltage being supplied to a particular sensor in the vehicle is exceeding the acceptable range. This can lead to various problems in the vehicle's performance and overall functionality.

Common Causes of P0699 KIA

  1. Faulty Sensor: A malfunctioning sensor that is receiving too much voltage can trigger a P0699 code.
  2. Wiring Issues: Damaged or corroded wiring connected to the sensor can cause voltage irregularities.
  3. Malfunctioning PCM: A problem with the powertrain control module that controls the sensor reference voltage can lead to this issue.
  4. Voltage Regulator Malfunction: If the voltage regulator is not functioning correctly, it can cause the sensor reference voltage to be too high.

Symptoms of P0699 KIA

  1. Check Engine Light: The most common symptom associated with a P0699 code is the illumination of the check engine light on the vehicle's dashboard.
  2. Poor Fuel Efficiency: A high sensor reference voltage can lead to incorrect readings from sensors, resulting in decreased fuel efficiency.
  3. Rough Idling: The engine may idle roughly or inconsistently due to the incorrect sensor readings caused by the high voltage.
  4. Stalling: In severe cases, the vehicle may stall while driving, especially at low speeds or when coming to a stop.

How to Fix P0699 KIA

  1. Diagnose the Issue: Use a diagnostic scanner to read the code and pinpoint the exact sensor causing the problem.
  2. Check Wiring: Inspect the wiring connected to the sensor to ensure there are no damages or loose connections.
  3. Test Sensor: Test the sensor itself to determine if it is faulty and needs replacement.
  4. Check PCM: Verify the functionality of the powertrain control module to rule out any issues with its operation.
  5. Replace Components: Replace the faulty sensor, wiring, or PCM as needed to correct the high sensor reference voltage issue.

Cost to Fix P0699 KIA

The cost of repairing a P0699 code can vary depending on the specific cause of the issue. On average, the parts for this repair can range from $50 to $200, while labor costs can range from $100 to $300. Keep in mind that diagnostic time and labor rates at auto repair shops can influence the overall cost. It's advisable to consult with a professional technician to get an accurate estimate based on your vehicle's make and model.

Frequently Asked Questions about P0699 KIA Code

1. What does the OBDII code P0699 mean on a Kia?

P0699 indicates a problem with the Sensor Reference Voltage 'C' Circuit being too high, which suggests an issue with the voltage supplied to one or more sensors in this circuit.

2. What are the common symptoms of the P0699 code in a Kia?

Symptoms may include engine performance issues, poor fuel efficiency, stalling, difficulty starting, or the Check Engine Light being illuminated.

3. What causes the P0699 code in a Kia?

Common causes include a faulty sensor, damaged wiring or connectors, a short circuit, or issues with the Engine Control Module (ECM).

4. Can I drive my Kia with the P0699 code?

Driving with this code is not recommended as it can lead to poor performance or further damage to the engine if the issue isn't addressed.

5. How is the P0699 code diagnosed on a Kia?

A technician will use a scan tool to confirm the code, inspect wiring and connectors for damage, and test sensors and the ECM for proper operation.

6. What sensors are affected by the P0699 code in a Kia?

The code relates to sensors that depend on the 'C' reference voltage circuit, which can vary depending on the vehicle model and configuration.

7. How do you fix the P0699 code in a Kia?

Repairs may include replacing damaged wiring, repairing connectors, replacing a faulty sensor, or in rare cases, reprogramming or replacing the ECM.

8. How much does it cost to fix the P0699 code in a Kia?

Repair costs vary widely, ranging from $50 for simple wiring repairs to $1,000 or more if ECM replacement is needed.

9. Can a weak battery cause the P0699 code in a Kia?

While unlikely, a weak or failing battery can contribute to electrical issues, so it’s worth ensuring the battery and charging system are functioning correctly.

10. Will clearing the P0699 code fix the problem in my Kia?

Clearing the code without addressing the underlying issue will only temporarily turn off the Check Engine Light, and the code is likely to return.
