DTC P2243:00, P2247:00: Notes

WARNING: This page is about a different variant/trim than selected.
DTC P2243:00 P2243:00: A/F sensor (RH) reference voltage circuit/open
DTC P2247:00 P2247:00: A/F sensor (LH) reference voltage circuit/open
DETECTION CONDITION 
  • P2243:00 indicates that A/F sensor (RH) positive current control circuit/open
  • P2247:00 indicates that A/F sensor (LH) positive current control circuit/open
  • The powertrain control module (PCM) monitors the universal heated oxygen sensor (HO2S) for a circuit concern. This DTC sets when the PCM detects a concern with the circuit used to determine the oxygen content in the exhaust gas.
POSSIBLE CAUSE 
  • Open A/F sensor circuit
  • P2243:00:
    • Open circuit in wiring harness between the following terminals:
      • A/F sensor (RH) terminal H-PCM terminal 2AC
      • A/F sensor (RH) terminal F-PCM terminal 2AG
      • A/F sensor (RH) terminal D-PCM terminal 2BD
    • Short to ground in wiring harness between the following terminals:
      • A/F sensor (RH) terminal H-PCM terminal 2AC
      • A/F sensor (RH) terminal F-PCM terminal 2AG
      • A/F sensor (RH) terminal G-PCM terminal 2AS
      • A/F sensor (RH) terminal D-PCM terminal 2BD
    • Short to power supply in wiring harness between the following terminals:
      • A/F sensor (RH) terminal H-PCM terminal 2AC
      • A/F sensor (RH) terminal F-PCM terminal 2AG
      • A/F sensor (RH) terminal G-PCM terminal 2AS
      • A/F sensor (RH) terminal D-PCM terminal 2BD
  • P2247:00:
    • Open circuit in wiring harness between the following terminals:
      • A/F sensor (LH) terminal H-PCM terminal 2AE
      • A/F sensor (LH) terminal F-PCM terminal 2AK
      • A/F sensor (LH) terminal D-PCM terminal 2BF
    • Short to ground in wiring harness between the following terminals:
      • A/F sensor (LH) terminal H-PCM terminal 2AE
      • A/F sensor (LH) terminal F-PCM terminal 2AK
      • A/F sensor (LH) terminal G-PCM terminal 2AO
      • A/F sensor (LH) terminal D-PCM terminal 2BF
    • Short to power supply in wiring harness between the following terminals:
      • A/F sensor (LH) terminal H-PCM terminal 2AE
      • A/F sensor (LH) terminal F-PCM terminal 2AK
      • A/F sensor (LH) terminal G-PCM terminal 2AO
      • A/F sensor (LH) terminal D-PCM terminal 2BF
  • Damaged A/F sensor
  • PCM malfunction
