No
GO to A5.
A5 CHECK THE RESISTANCE OF THE SOLENOID FIELD CIRCUIT
- Ignition OFF.
- Measure the resistance between the transaxle solenoid body C168-15, component side and the suspect solenoid pin, component side and compare the value to the specifications in the table below.

Is the resistance within specifications?
Yes
INSTALL a new PCM. RECONNECT all components. TEST the system for normal operation.
No
REMOVE the main control cover. REFER to Main Control Cover . INSPECT the solenoid body for foreign material such as metal shavings on the exposed metal contacts or other components. CLEAR the solenoid body and RECHECK the resistance values. If the resistance values are still out of specification, INSTALL a new solenoid body assembly. REFER to Solenoid Body Assembly . RECONNECT all components. TEST the system for normal operation.
