DTC Information: DTC Detecting Condition

WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.
Item Detecting Condition Possible Cause
DTC Strategy Case1
  • Rationality check, jitter
  • Poor connector connection
  • FRPS
  • Abnormal fuel pressure
  • Low or no fuel
