(a) Rotated ignition switch to OFF position . (b) Disconnect intake manifold absolute pressure sensor wiring (c) Rotated ignition switch to ON position . (d) Measure voltage between intake manifold absolute pressure sensor 进气压力温度传感器线束连接器 EM30 1 2 3 4 NL02-0035c Standard voltage: 4.5V-5.5V (e) Connect intake manifold absolute pressure sensor wiring harness connector EM30. Is voltage the specified value?
Step 3 Measure Sensor Signal Circuit (a) Rotated ignition switch to OFF position . (b) Disconnect intake manifold absolute pressure sensor wiring harness connector EM30. (c) Rotated ignition switch to ON position . (d) Connect a 5A fuse cross-wiring between EM30 terminals No. 2 and No.4. With a fault standard value: 4.5V-5.5V (e) Connect intake manifold absolute pressure sensor wiring harness connector EM30. Is data normal?
Step 4 Measure intake manifold absolute pressure sensor ground circuit. (a) Rotated ignition switch to OFF position . (b) Disconnect intake manifold absolute pressure sensor wiring harness connector EM30. (c) Rotated ignition switch to ON position . (d) Measure resistance between intake manifold absolute pressure sensor wiring harness connector EM30 terminal No.4 and a reliable ground. Standard Value: Less than 3 Ω (e) Connect intake manifold absolute pressure sensor wiring harness connector EM30.
