: Later intercooled versions (like the 1KZ-TE found in the Hilux Tiger) may have different pin mappings for air temperature sensors (THA) compared to non-intercooled versions. Troubleshooting Benchmarks

Always start with the pinout. Never throw parts at a diesel ECU until you verify voltage, ground, and signal at the pins. 1kz ecu pinout
