MANUAL TRANSMISSION TROUBLESHOOTING2218
Code No.74 Proportional valve systemAssumed cause of concern
In cases where the proportional valve control circuit
is shorting, code No.74 is output.• Proportional valve malfunction
• Harness, connector malfunction
Remarks*2: refer to ’011 Lancer Evolution VII Service Manual (No.1036K02)
MUTII/III Service data
• No.11 Proportional valve current
OK:P.2232 Refer to (Service Data List)*2
OK > Intermittent malfunction
Measurement at F25 proportional valve
connector
