Performance Engine Swap Applications

• Toyota 2JZ-GTE swap: GM MAF sensor adaptation harness – the 15305554 connector is used when fitting a GM LS-series MAF sensor to a 2JZ-GTE intake for standalone ECU tuning
• GM LS2 (Pontiac GTO 2004–2006): OEM MAF sensor harness connector
• Lexus IS300 / GS300: 2JZ-GE MAF sensor harness
• GM LS swap builds: MAF sensor pigtail for LS1/LS2/LS3 engine swaps

Fault Codes Linked to MAF Connector Failure

• P0100–P0103 – MAF sensor circuit faults
• P0110–P0113 – IAT sensor circuit faults (shared connector)
• P0171 / P0172 – System Lean/Rich (caused by MAF signal loss)

Frequently Asked Questions

Q: Is this connector used in 2JZ-GTE engine swaps?
A: Yes. The 15305554 / 15306113 is the standard GM Delphi MAF connector used when adapting a GM LS-series MAF sensor to a 2JZ-GTE or other Japanese engine swap. It is also the OEM connector on GM LS2 engines in the Pontiac GTO.

Q: What is the difference between 15305554 and 15306113?
A: Both are Delphi / GM part numbers for the same 5-pin 1.5mm MAF connector housing – 15305554 is the earlier catalog number; 15306113 is the updated supersession number. Both are fully interchangeable.

Q: What crimping tool is needed?
A: Use the Kent-Moore J-38125-8 or Delphi 12085271 ratchet crimper for 1.5mm Micro-Pack 100 terminals.
