Shift Solenoids & Torque Converter Clutch (TCC) Solenoid
- Obtain access to PCM. See Figure
. Ensure ignition is off. Disconnect PCM harness connector. Turn ignition on. On 1.6L, using a fused jumper wire, connect one end to PCM harness connector E172 terminal No. 4 (White wire). With other end, probe harness connector E173 terminals No. 15 (Green/Orange wire), No. 8 (Green/Red wire) and No. 16 (Green/Yellow wire), one at a time. On 1.8L, using a fused jumper wire, connect one end to PCM harness connector E172 terminal No. 25 (White wire). With other end, probe harness connector E174 terminals No. 6 (Green wire), No. 2 (Green/Yellow wire) and No. 13 (Green/Red wire), one at a time. On all models, ensure a "clicking" sound can be heard when battery voltage is applied. Replace appropriate solenoid if no sound is heard.
- To check solenoid seals, apply battery voltage to solenoid. Apply ATF to solenoid with battery voltage connected. See Fig 1
. ATF should pass through solenoid. Remove battery voltage. Ensure ATF does not pass through solenoid. Replace appropriate solenoid if defective.
