Standard PC403T Engine Camshaft Position Sensor - Exhaust

Engine Camshaft Position Sensor for GM Applications

The Standard PC403T engine camshaft position sensor is built for direct replacement in a range of GM and related vehicles, including Chevrolet Colorado, GMC Canyon, and Saturn Ion applications. It uses integrated analog-to-digital conversion and digital signal processing to deliver stable signal output for accurate camshaft timing feedback.

Key Features

• Female connector with plug-in design for straightforward electrical connection
• 3 blade terminals with male terminal gender
• Integrated A/D converter and digital signal processing for refined signal control
• Dynamically adaptive switch points to improve signal accuracy and operation
• Advanced circuitry helps protect against stray electromagnetic fields and power spikes
• Magnetic circuit programming calibrated during performance testing for timing accuracy
• 100% environmental, endurance, and end-of-line testing for timing, pulse width, and signal amplitude

Detailed Description

Standard PC403T is an OE-style camshaft position sensor engineered to monitor camshaft position and send a clean signal to the engine control system. That signal supports precise ignition and fuel strategy on vehicles such as the Chevrolet Colorado, GMC Canyon, and Saturn Ion, along with other listed GM-platform applications. This part cross-references Dorman - OE Solutions 917-714 and Beck/Arnley 180-0587 for the same application. The PC403T part number is also commonly referenced in replacement searches for camshaft position sensor service on GM trucks and SUVs.

What It Helps Address

• Camshaft position signal loss or intermittent sensor output
• Check engine light concerns related to camshaft sensor performance
• Hard starting caused by inaccurate camshaft timing input
• Rough idle or drivability issues tied to unstable sensor readings
• Timing-related fault codes on Chevrolet Colorado, GMC Canyon, and similar applications

Installation Notes and Tips

Verify connector style, terminal count, and engine application before installation. This sensor uses a female plug-in connector with 3 male blade terminals. Confirm whether your vehicle requires the standard or exhaust-position listing shown in the fitment data, especially on Chevrolet Colorado, GMC Canyon, Hummer H3, and Isuzu i-350 exhaust applications. For best results, inspect the harness connector and surrounding wiring for corrosion, damaged terminals, or heat-related wear before installing the PC403T.

Quality Assurance

Standard tests this sensor for timing, pulse width, and signal amplitude at the end of production, along with environmental and endurance validation. The internal circuitry is engineered to resist electromagnetic interference and power spikes, supporting consistent signal performance across the listed fitment range. The PC403T is built to meet the demands of camshaft position sensor replacement on GM and related vehicles.
