AEM 30-2130-150 Pressure Sensor, 150 PSIG, 1/8" NPT, Replacement with 12 Month Warranty & USA Business

Get accurate and dependable pressure monitoring with the Wholesale Sensors 30-2130-150 Replacement Pressure Sensor, 150 PSIG with 1/8″ NPT Male Thread. Engineered as a perfect OEM-style replacement for the AEM 30-2130-150 sensor specification, this pressure transducer is designed to meet or exceed original functional requirements while providing reliable pressure feedback for compatible automotive, motorsports, engine management, gauge, and data acquisition systems.

The sensor is designed for applications requiring a 0 to 150 PSIG gauge pressure range, making it particularly useful for monitoring fuel pressure, engine oil pressure, brake pressure, nitrous pressure, and other compatible fluid-pressure systems.

AEM identifies the original 30-2130-150 as a gauge-style pressure sensor. Gauge pressure is measured relative to atmospheric pressure, meaning a properly configured gauge-style sensor reads approximately 0 PSIG when exposed to normal atmospheric pressure. AEM Electronics

Replacement for AEM 30-2130-150

This Wholesale Sensors pressure sensor is designed as a replacement for:

AEM 30-2130-150
AEM Electronics 30-2130-150

The original AEM component is officially identified as the 30-2130-150 150 PSIg Stainless Sensor Kit. AEM specifies a 1/8-inch NPT male thread and a 150 PSIG measurement range. Holley

The Wholesale Sensors product is an aftermarket replacement and is not represented as a genuine AEM component.

Because this is a pressure transducer rather than a vehicle-specific factory sensor, compatibility should be determined by the pressure range, electrical output, supply voltage, thread size, wiring configuration, and ECU or gauge calibration rather than vehicle make and model alone.

0 to 150 PSIG Pressure Range

The sensor provides pressure measurement across a 0 to 150 PSIG range.

This range makes it suitable for numerous automotive and motorsports applications where precise fluid-pressure information is needed. AEM specifically identifies gauge-style pressure sensors for applications including:

Fuel pressure
Engine oil pressure
Brake pressure
Nitrous pressure

AEM’s own documentation also identifies the 30-2130-150 as both a 150 PSI fuel pressure sensor and an optional 150 PSI engine oil pressure sensor in a competition engine-management application. AEM Electronics

The sensor should only be used when the expected operating pressure remains appropriate for its specified measurement range.

1/8-Inch NPT Male Thread

The 30-2130-150 configuration uses a 1/8-inch NPT male pressure connection, commonly identified more specifically as 1/8″-27 NPT. JEGS High Performance

This common pressure-sensor thread makes the sensor suitable for integration with many aftermarket fuel, oil, brake, and pressure monitoring installations.

Always verify the receiving port before installation. Never force an NPT sensor into a port with a different thread specification.

Adapters may be required when the pressure source does not provide the appropriate 1/8″ NPT female connection.

Linear 0.5 to 4.5 Volt Output

The original 30-2130-150 specification uses a 0.5 to 4.5 VDC linear analog output with a 5 VDC supply. Published technical specifications identify supply current as less than 6 mA at 5 VDC. Visconti Tuning

The documented transfer function for the original sensor is:

PSI = (37.5 × Voltage) – 18.75

This electrical output allows compatible aftermarket engine management systems, gauges, displays, and data acquisition equipment to convert sensor voltage into pressure information. Visconti Tuning

Correct calibration is essential. Simply connecting a 0.5 to 4.5V sensor to an ECU does not guarantee an accurate pressure display. The controller must be configured for the correct sensor scaling.

Semi-Universal Automotive and Motorsports Compatibility

Unlike a vehicle-specific factory pressure switch, the 30-2130-150 is a semi-universal performance pressure sensor. JEGS similarly categorizes the original AEM component as semi-universal fitment. JEGS High Performance

This makes the replacement suitable for custom installations involving compatible:

Engine management systems
Aftermarket ECUs
Digital dashboards
Pressure gauges
Data logging systems
Race car electronics
Performance fuel systems
Oil pressure monitoring systems

Compatibility should be verified by electrical and mechanical specifications rather than assuming fitment based on vehicle year, make, or model.

Fuel Pressure Monitoring

Fuel pressure is one of the most common applications for the 30-2130-150 configuration.

Accurate fuel pressure information can be valuable when diagnosing fuel delivery problems, configuring an engine management system, monitoring a performance fuel system, or protecting an engine during high-load operation.

AEM documentation for a competition GM LS3 engine platform specifically identifies 30-2130-150 as the required fuel pressure sensor for that setup. AEM Electronics

Depending on the installation, the pressure signal can be displayed on a gauge, recorded by a data logger, or supplied to an ECU for monitoring and control strategies.

Engine Oil Pressure Monitoring

The 150 PSIG range also makes this sensor suitable for compatible engine oil pressure monitoring applications.

AEM’s competition-engine documentation specifically lists 30-2130-150 as an optional 150 PSI oil pressure sensor. AEM Electronics

An accurate oil pressure signal can help drivers, technicians, tuners, and engine management systems identify abnormal pressure conditions before they result in more serious problems.

The sensor itself does not diagnose the mechanical cause of abnormal oil pressure. Low or excessive readings should always be investigated according to the engine manufacturer’s specifications.

Stainless Steel Construction

Pressure sensors installed in performance vehicles may be exposed to vibration, heat, fuel, oil, and other automotive fluids.

The original 30-2130-150 specification uses a stainless steel sensor body with 304L and 316L stainless steel wetted materials. Published specifications also describe a 360-degree welded wetted area designed to resist exposure to automotive fluids. Nippon Power

Wholesale Sensors builds its replacement for dependable use in these demanding pressure-monitoring environments and rigorously tests it for pressure response, electrical output, connection integrity, and consistent functional performance.

Fast Pressure Response

Published specifications for the original AEM 30-2130-150 list a response time of less than 1 millisecond. The operating temperature specification is -40°C to 105°C, or -40°F to 221°F, with vibration resistance specified from 100 to 2000 Hz at 20g sinusoidal across three axes. Nippon Power

These characteristics make this sensor configuration suitable for demanding performance and motorsports applications where pressure can change rapidly.

Helps Correct Faulty Pressure Readings

A failing pressure sensor can contribute to:

Inaccurate pressure readings
Intermittent pressure signals
Pressure readings stuck at an incorrect value
Missing pressure data
Unstable gauge readings
Incorrect ECU or data logger pressure information

However, these symptoms do not automatically mean the sensor is defective.

Damaged wiring, poor grounds, incorrect 5V reference voltage, connector problems, calibration errors, pressure leaks, restricted passages, and actual mechanical pressure problems can produce similar symptoms.

Test the sensor circuit and mechanical system before replacing components.

Installation and Calibration

Before installation, confirm that the system is depressurized and safe to service. Install the sensor into the appropriate 1/8″ NPT pressure port or use the correct adapter for the application.

The electrical system must provide the proper 5V reference, sensor ground, and signal connection. Verify terminal positions before connecting wiring. Do not determine pin functions from wire color alone unless the wiring documentation specifically confirms them.

After installation, configure the connected ECU, gauge, dashboard, or data logger for the correct 0 to 150 PSIG, 0.5 to 4.5V pressure calibration.

Verify readings against a known pressure source when appropriate.

No Universal OBD-II Code

There is no single automotive OBD-II diagnostic trouble code that the 30-2130-150 universally resolves.

This is an aftermarket pressure sensor that can monitor different pressure systems and can be connected to different ECUs, gauges, or data acquisition equipment. Whether a fault generates an OBD-II code depends entirely on the installation and control system.

A pressure-related warning or diagnostic code should therefore be diagnosed according to the specific vehicle, ECU, and monitored pressure circuit.
