Some DTS applications have blank IAC and TPS fields in Mercury application data. A blank field does NOT mean "use the non-DTS part." Do not infer conventional TPS compatibility for DTS engines.

This TPS applies to the 7.4L MPI L29, ECM-555 MPI (mechanical-throttle variants), 496 Mag, and 8.1L MIE engine families. DTS applications may have blank TPS fields in Mercury application data — do not infer conventional TPS compatibility for DTS engines. Verify your exact engine model, serial number, and existing OEM part number before ordering.

Automotive cross-reference leads exist for this sensor but remain unverified internal commercial research. No automotive part numbers are published as verified customer-facing data at this stage.

Verified Engine Applications

Application relationships are verified against Mercury Marine primary source documentation. DTS applications with blank TPS fields in the OEM matrix are excluded.
