2.0L Engine Controls PCM Connector C3 Pinout - 28-Pin Wiring Diagram & Wire Colors

This scanned service-manual page (page 6-1074, 'Engine Controls - 2.0L') shows the back view and complete pinout of PCM Connector C3 for a 2.0L VIN C powertrain. The header notes it is a 28-pin connector (C3) with an orange terminal secondary lock. A diagram at the top shows the connector's rear view with pin cavities numbered 1-28 arranged in three rows (1-7, 8-19, 20-28), with unused cavities marked. Below it, a table lists each pin (C3-1 through C3-28) with its wire color and circuit function. Functions covered are primarily automatic-transmission related: shift solenoid #1 and #2 controls, TCC solenoid control, A/T input and output shaft speed sensor signal high/low and shielded grounds, transmission range (TR) switch position signals (P, R, N, D, L), and a 4WD Low signal. Wire colors include GRN/RED, GRN, GRN/YEL, BLU/GRN, BLU/YEL, YEL/GRN, ORN/BLU, RED, ORN/GRN, BLK, ORN, WHT, ORN/WHT and GRN/BLU. Several pin ranges (C3-3 to C3-7, C3-9, C3-12 to C3-14, C3-19, C3-24 to C3-25) are not used. The row for C3-28 is cut off at the bottom of the scan. Readers can use this page to identify PCM transmission-control circuits and wire colors for diagnosis.
