ACDelco GM PT1504 5 Way Mass Air Flow Sensor Pigtail, Replacement with 12 Month Warranty & Made in USA

Restore a damaged mass air flow sensor or compatible electrical connection with the Wholesale Sensors Replacement for ACDelco GM PT1504 5-Way Multi-Purpose Pigtail. Made in the USA and engineered as a perfect OEM-style replacement, this 5-wire connector is designed to meet or exceed original fit and functional specifications while providing a dependable splice-in repair for compatible automotive wiring harnesses.

The ACDelco PT1504 corresponds directly to General Motors part number 88953157. GM identifies 88953157 as a 5-way female black multi-purpose pigtail with five wires and five terminals. ACDelco catalogs also identify PT1504 specifically as a mass air flow sensor connector. GM Parts Store

This makes the replacement a practical solution when the original connector has become damaged but the remaining vehicle wiring harness is still serviceable.

Replacement for ACDelco PT1504 and GM 88953157

This Wholesale Sensors pigtail is designed as an aftermarket replacement for:

ACDelco PT1504
GM 88953157

GM’s official parts catalog directly associates ACDelco PT1504 with GM 88953157. GM Parts Store

A documented aftermarket interchange is:

Dorman 645-747

Manufacturer cross-reference data identifies Dorman 645-747 as an interchange for ACDelco PT1504. Auto Barn

The Wholesale Sensors product is an aftermarket replacement and is not represented as a genuine ACDelco or General Motors component.

5-Way Multi-Purpose Pigtail Design

The PT1504 configuration features:

5 wire leads
5 female blade terminals
Black connector housing
Rectangular connector shape
Approximately 13-inch overall length
Splice-in wiring harness design

GM’s official specifications confirm five wires, five female blade terminals, a black housing, and rectangular shape. Additional ACDelco catalog information lists an overall length of approximately 13 inches. GM Parts Store

The five-wire configuration makes this connector suitable for compatible mass air flow sensor circuits and other documented applications requiring the same PT1504 / 88953157 connector.

Mass Air Flow Sensor Connector Application

ACDelco PT1504 is specifically cataloged as a mass air flow sensor connector. AutoZone

A vehicle’s mass air flow sensor measures incoming airflow so the engine management system can calculate appropriate operating parameters. Reliable electrical communication between the MAF sensor and engine control system is therefore important for proper sensor operation.

Even a properly functioning MAF sensor cannot provide dependable information if its electrical connector has damaged terminals, broken wires, excessive corrosion, or intermittent electrical contact.

Replacing the damaged pigtail can restore a secure electrical connection without requiring replacement of the complete engine wiring harness.

Compatible GM Vehicles

GM officially documents PT1504 / 88953157 fitment for vehicles including:

Chevrolet C4500 Kodiak 2003-2006
Chevrolet C5500 Kodiak 2003-2006
Chevrolet Express 2500 2006-2007
Chevrolet Express 3500 2006-2007
Chevrolet Prizm 2000-2002

GM’s catalog also indicates Chevrolet and GMC application coverage for the pigtail, while other application catalogs document additional GM-family fitments. GM Parts Store

Because PT1504 is described by GM as a multi-purpose pigtail, compatibility should never be determined from vehicle make alone.

Always verify the year, make, model, engine, electrical circuit, connector shape, terminal count, and original OE number before purchasing.

Helps Repair Common Connector Problems

Automotive electrical connectors can deteriorate from heat, engine vibration, moisture, corrosion, age, previous repairs, and repeated disconnection.

A damaged PT1504 connector may exhibit:

Cracked or broken connector housing
Broken or brittle wiring
Loose electrical terminals
Corroded terminals
Damaged locking mechanism
Intermittent electrical connection
Heat-damaged insulation
Open sensor circuits

When used on a mass air flow sensor circuit, these electrical problems can interfere with the MAF signal and contribute to inaccurate or intermittent airflow information.

Depending on the specific vehicle and failure, symptoms may include rough running, poor acceleration, unstable idle, reduced performance, poor fuel economy, warning lights, or inconsistent MAF readings.

These symptoms do not automatically prove that the pigtail is defective. The MAF sensor, wiring, intake system, power supply, ground circuit, ECU, and other engine-management components should be diagnosed before replacement.

MAF Diagnostic Trouble Codes

A damaged MAF sensor circuit can potentially be associated with diagnostic trouble codes such as P0100, P0101, P0102, P0103, or P0104, depending on the vehicle and nature of the electrical fault.

However, these codes do not prove that PT1504 itself has failed.

A MAF-related code can result from a faulty sensor, damaged wiring, poor electrical connection, air leak, contaminated sensor element, incorrect power or ground, or another engine-management problem.

Always follow the diagnostic procedure for the exact vehicle before replacing components.

Straightforward Splice-In Installation

GM describes its pigtail connectors as components designed to be spliced into the existing vehicle wiring harness. AutoZone

Before beginning installation, disconnect the vehicle battery according to the manufacturer’s recommended procedure.

Compare the replacement PT1504 connector with the original before cutting any wires. Confirm the connector shape, five-terminal configuration, locking mechanism, and circuit arrangement.

Document each original wire and terminal position.

Do not connect replacement wires based only on wire color. Pigtail lead colors can differ from the original vehicle harness. Use the appropriate wiring diagram to identify each circuit and match it to the correct terminal position.

Remove damaged wiring as necessary and make secure automotive-grade splices. Protect each repair against moisture, vibration, heat, and abrasion.

Route the repaired harness away from exhaust components, belts, pulleys, cooling fans, and sharp edges.

After installation, reconnect the battery and verify normal operation of the repaired circuit.
