Intermittent Limp Mode (Code 14 - Timing Control) Code 14 indicates a timing control system malfunction.

Often utilizes a 4-plug layout or a different pin density to accommodate advanced emissions and intercooling.

Note: Pinout numbering conventions can vary depending on whether you are looking at the front of the ECU plug or the wire-side of the harness. Always verify ground and constant power pins with a multimeter before modifying any wires. 1kz ecu pinout

If your vehicle does not have an OBD2 port (common on pre-2000 JDM models), you can read fault codes manually using the pins.
