DESCRIPTION
Those DTCs are designed to detect a deviation in the output characteristics of a pressure sensor.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
---|---|---|---|---|---|---|
P106A62 | Evaporative Emission System Pressure / Intake Air Pressure Signal Compare Failure | The difference between the pressure of the canister pressure sensor (Vapor Pressure Pump*) and manifold absolute pressure sensor (Intake Manifold Absolute Pressure*) is higher than 8.69 kPa (1.26 psi) (2 trip detection logic). |
| Comes on | DTC stored | SAE Code: P106A |
P106C62 | Evaporative Emission System Pressure/Barometric Pressure Signal Compare Failure | The difference between the pressure of the canister pressure sensor (Vapor Pressure Pump*) and atmospheric pressure sensor (Atmospheric Pressure*) is higher than 7.89 kPa (1.14 psi) (2 trip detection logic). |
| Comes on | DTC stored | SAE Code: P106C |
*: Data List name
MONITOR DESCRIPTION
Those DTCs are stored when a deviation from pressure sensor characteristics is detected.
The pressure sensors* are checked approximately 50 minutes after the power switch is turned off. If the pressures detected by the pressure sensors* differ by a certain amount, the MIL is illuminated and a DTC is stored (2 trip detection logic).

PROCEDURE
1. | CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P106A62 AND/OR P106C62) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Read the DTCs.
