EVAP CONTROL SYSTEM PRESSURE SENSOR 1. Remove EVAP control system pr essure sensor with its harness connec tor connected from EVAP canister.
Always replace O-ring with a new one.
2. Install a vacuum pump to EVAP control system pressure sensor.
3. Turn ignition switch ON and check output voltage between ECM terminal 42 (EVAP control system pressure sensor signal) and
ground under the following conditions.
CAUTION:
• Always calibrate the vacuum pu mp gauge when using it.
• Do not apply below -93.3 kP a (-700 mmHg, -27.56 inHg) or
pressure over 101.3 kPa (760 mmHg, 29.92 inHg).
4. If NG, replace EVAP control system pressure sensor. Continuity should exist.

DTC P0607 ECM
Description INFOID:0000000004501091
CAN (Controller Area Network) is a serial communication li ne for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis Logic INFOID:0000000004306009
This self-diagnosis has the one trip detection logic (A/T and CVT).
The MIL will not light up for this self-diagnosis (M/T).
DTC Confirmation Procedure INFOID:0000000004306010
1. Turn ignition switch ON.
2. Check 1st trip DTC.
3. If 1st trip DTC is detected, go to EC-1395, " Diagnosis Procedure " .
Diagnosis Procedure INFOID:0000000004306011DTC Confirmation Procedure " .
3. Is the 1st trip DTC P0607 displayed again?
Yes or No Yes >> GO TO 2.
No >> INSPECTION END ECM Re-communicating Function " .
3. Perform EC-1084, " VIN Registration " .
4. Perform EC-1084, " Accelerator Pedal Released Position Learning " .
5. Perform EC-1084, " Throttle Valve Closed Position Learning " .
