DTC P2259: Notes
DTC P2259 DETECTION & CONDITION POSSIBLE CAUSES
| DTC P2259 |
Secondary air injection solenoid valve control circuit low |
| DETECTION CONDITION |
- The PCM monitors the AIR solenoid valve control voltage when the AIR pump is not operating. If the control voltage is less than 5.8 V
, the PCM determines that the AIR solenoid valve control circuit voltage is low.
Diagnostic support note
- This is a continuous monitor (AIR system).
- The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- The DTC is stored in the PCM memory.

| POSSIBLE CAUSE |
- AIR solenoid valve malfunction
- Connector or terminal malfunction
- Open circuit in wiring harness between main relay terminal C and AIR solenoid valve terminal A
- Short to ground in wiring harness between main relay terminal C and AIR solenoid valve terminal A
- Open circuit in wiring harness between AIR solenoid valve terminal B and PCM terminal 1O
- Short to ground in wiring harness between AIR solenoid valve terminal B and PCM terminal 1O
- PCM malfunction
