What Does The P1326 KIA Code Mean?

The P1326 error code is associated with the Knock Sensor Detection System (KSDS) in certain Kia models. This code serves as an early warning system, detecting vibrations that indicate potential excessive wear in the connecting rod bearings of the engine.

When this code appears, the vehicle is placed in Limp Home Mode, which limits acceleration and restricts engine RPMs to approximately 1800-2000 RPM. The purpose of Limp Home Mode is to minimize further damage to the engine and prevent potential engine failure. Prompt action is crucial to address the underlying problem and avoid severe consequences.

The code P1326 is commonly set in many different KIA models, such as Optima, Sorento, Soul, Sportage, etc. According to Technical Service Bulletin (TSB) PI1803W/X, Kia dealers are instructed to perform specific procedures for certain models (2011-2014 Kia Optima, 2011-2013 Kia Sportage, 2012-2014 Kia Sorento) affected by the P1326 error code. Even if your Kia model is not listed or no longer under warranty, it is still recommended to take your car to a Kia dealer for a check-up and seek their advice.

How Severe Is The P1326 Code In KIA?

The P1326 error code in KIA vehicles has a high severity level. In theory, when a car experiences the P1326 error code, it may go into limp mode, where it is still technically driveable. 

However, it is advisable not to continue driving your car in this state. Limp mode is a safety feature that limits the vehicle’s performance to prevent further damage. It is strongly advised to avoid driving the vehicle in limp mode and instead seek professional assistance to diagnose and address the problem promptly.

What Are The Signs Of The P1326 KIA Code?

The P1326 error code in KIA vehicles is accompanied by a range of noticeable symptoms:

  • Check Engine Light (CEL) blinking
  • Reduced engine power or acceleration
  • Rough idling
  • Engine stalling or difficulty starting
  • Limp mode activated
  • Knocking sound

What Causes The P1326 Code in KIA Vehicles? 

Various underlying causes can trigger the P1326 error code in KIA vehicles. Some common causes for this code are:

  • Faulty knock sensor
  • Wiring issues
  • Excessive wear in connecting rod bearings

What To Do When Encountering The P1326 In Your KIA?

When encountering the P1326 error code in a KIA vehicle, it is important to take appropriate actions to address the issue effectively. In most cases, this code’s presence indicates a potential problem with the engine, which typically requires professional inspection and may involve updating or replacing the engine. Therefore, it is crucial not to drive the vehicle and immediately take it to a KIA dealer for a thorough inspection.

Attempting to clear the code yourself is not recommended, as the dealer will need to see the CEL blinking to accept addressing the issue. According to a post by Joel Strawn on Optimaforums.com, he shared his experience as follows: “I recently encountered this code and cleared it to drive home. However, when I contacted the dealer, they informed me that they would not take any action unless the MIL was flashing and the previous code was stored in the ECU. Eventually, I managed to get the light to come back on, and now they have agreed to honor the warranty for my 2016 Sorento, despite it having 113,000 miles on it. Now, I will wait and see how long it takes for the repairs to be completed.“

Why Choosing The KIA Dealer Over DIY?

It is important to understand that the faulty engine associated with the P1326 code is not something you can handle on your own. Take your car to a KIA dealer to assess if an engine update or replacement is necessary. They have the expertise and technical knowledge to diagnose the problem accurately and recommend the appropriate course of action. 

KIA services are known for their excellent customer support and satisfaction. In most cases, car owners have reported receiving a new engine, albeit with additional fees for minor components or services. Therefore, it is reassuring to rely on KIA services to address the issue effectively. 

If it turns out that the engine isn’t causing the issue, it might be due to problems with sensors or wiring. In this case, you’re in luck, as fixing these sensors or wiring issues usually costs around $100 to $400. This is much more affordable than having to replace the whole engine, which could cost a lot more.
