DTC Information: DTC Detecting Condition

DTC DETECTING CONDITIONS AND POSSIBLE CAUSES

Item Detecting Condition Possible Cause
DTC Strategy
  • Rationality check
  1. Poor connection
  2. Open or short power/ground in signal circuit
  3. S1

  • Fuel feed back control active
  • Battery voltage is greater than 11V
  • Exhaust Gas temperature is between 536°F and 1472° F
  • No injector error
  • No upstream O2 sensor heater error
Case1 Enable Conditions
  • S2 sensor voltage is higher than 0.5V
Threshold Value
  • S1 sensor voltage is between 0.06V and 0.4V
Diagnostic Time
  • 25 sec.
Case2 Enable Conditions
  • S2 sensor voltage is lower than 0.1V
Threshold Value
  • S1 sensor voltage is between 0.6V and 1.08V
Diagnostic Time
  • 10 sec.
Case3 Enable Conditions
  • Time after dew point end detected is higher than 10s
Threshold Value
  • The number of that the absolute value of Δusvk is greater than 2V during 0.04 sec after turning on and off a heater is more than or equal to 5 times.
MIL ON Condition
