WEITARI Oil Pressure Sensor Switch for GM Trucks and Vans — 19244500 / PS262 Threaded Direct-Replacement, Single Unit

This compact, threaded sensor monitors engine oil pressure and sends that signal to the vehicle’s gauge or warning light. It fits many Chevrolet and GMC models — including Blazer, C1500, K1500, Astro, Tahoe and various Express/Savana and Suburban variants — and is supplied as a single ready-to-install unit with OEM-equivalent mounting and electrical terminals. The switch is offered as a practical replacement when your original sensor fails, leaks, or produces inconsistent readings.

Which vehicles will this WEITARI sensor fit?

The sensor is compatible with a broad list of GM platforms spanning multiple years and model names. Fitment covers light-duty and heavy-duty pickups, vans, SUVs and utility vehicles commonly used for work and family transport. Always cross-check part numbers and engine locations before purchase to confirm compatibility with your specific VIN or engine code.

• Common fits: Chevrolet C1500/C2500/C3500, K1500/K2500, S10, Tahoe, Blazer, Suburban
• Vans and work vehicles: Express 1500/2500/3500, G-series vans (G10/G20/G30)
• Other GM cars: Corvette, Eldorado, Seville, and several 1990s passenger models

How do I know if I need to replace my oil pressure switch?

Signs that the switch is failing include an oil-warning light that stays on or flickers, a pressure gauge that shows incorrect readings, or visible oil leaking at the sensor. Electrical misbehavior — intermittent alerts or no signal to the dash — also points to a bad switch. If you see any of these symptoms, inspect the sensor and wiring before opting for a simple replacement with this WEITARI unit.

• Warning light on constantly or intermittently
• Oil pressure gauge reads erratically or flatlines
• Oil seepage or corrosion at the sensor threads and connector

What are the installation and performance details?

The sensor installs in the factory oil-pressure port using standard hand tools and a matching thread size; it connects to the existing wiring harness with the original clip. WEITARI supplies the part to match common OEM specifications so the dash and engine control systems receive the expected signal. Installation is typically straightforward for anyone comfortable with basic under-hood or under-car repairs.

• Direct-replacement design: same mounting and connector style as OEM
• Single-piece package: one sensor included ready to install
• Manufactured to meet common electrical and thread specifications for GM models

Are there equivalent part numbers or cross-references?

This WEITARI switch is offered as an alternative to many OE and aftermarket reference numbers, helping you match an old or broken sensor to a compatible replacement. If you have a part number from the old sensor, compare it against the cross-list to ensure the correct item. Using the right cross-reference prevents mismatches in thread pitch or electrical terminals.

• Common replacement numbers include: 19244500, 1S6635, PS262
• Also cross-references many OEM catalog numbers listed for GM models
• Verify against your vehicle’s original sensor part number before ordering

It caters to anyone seeking an OEM-style part to restore oil-pressure signaling without custom wiring or modifications.
