Geely Emgrand X7. Manual part - 42
(b) Disconnect VVT solenoid valve harness connector EM13. (c) Rotated ignition switch to ON position . (d) Test EM13 connector terminal A with a multimeter. Standard Voltage: 11-14V (e) Connect VVT solenoid valve harness connector EM13.
Step 3 Inspect VVT solenoid valve control circuit.
(a) Rotated ignition switch to OFF position . (b) Disconnect VVT solenoid valve harness connector EM13. (c) Disconnect ECM harness (d) Use multimeter to measure the resistance between VVT solenoid ECM线束连接器 EM01 1 2 4 5 3 81 63 44 25 6 62 43 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 26 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 45 46 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 64 65 66 80 79 78 77 76 75 74 73 72 71 70 69 68 67 NL02-0033c (e) Use multimeter to measure the resistance between VVT solenoid valve wiring harness connector EM13 terminal B and the ground. For the Standard Value. Refer to the table below. (f) Turn the ignition switch to ON position, (Note: At this point EM01, EM13 connectors must be disconnected) Measure voltage between VVT solenoid valve wiring harness connector Test Connection Standard Value Resistance Between EM13(B) and EM01 (43) Less than 1 Ω Resistance Between EM13 (B) and Ground 10 kΩ or higher Voltage Between EM13 (B) and Ground Less than 0 V
Step 4 Inspect the ECM Power Supply Circuits. (a) Inspect whether ECM power supply circuit is normal. (b) Inspect whether ECM ground circuit is normal. No Repair or replace harness connector Yes No Inspect whether circuit between EM09 solenoid valve Yes ECMharness connectorEM01 167 |
