Camshaft Position Sensor > CHEVROLET COLORADO / TRAILBLAZER 2.5L / 2.8L DURAMAX DIESEL (RG/S-10 Platform) > 93310500 | GENUINE PART (GM Original Equipment)
-
Genuine OEM Engine Component (General Motors/Chevrolet Original Equipment, often sourced from ACDelco or an OE vendor like Bosch).
-
Part Number: 93310500 (GM OE Number).
-
Component Name: Camshaft Position Sensor (CMP Sensor).
-
Primary Applications: Vehicles equipped with the 2.5L and 2.8L 4-Cylinder Duramax Diesel engines (often the XLD25/XLD28 series):
-
Chevrolet Colorado (RG Platform): 2.5L and 2.8L Diesel models (approx. 2012–2016). This is a confirmed match for your 2012-2013 Diesel Colorado.
-
Chevrolet Trailblazer (RG Platform): 2.5L and 2.8L Diesel models (approx. 2012–2016).
-
-
Engine Type: This sensor is specifically for the modern Common Rail Direct Injection (CRDi) Diesel engines, not the gasoline variants of the Colorado (which use different sensors).
-
Key Function: Provides precise camshaft timing data to the Engine Control Module (ECM), which is essential for accurate control of diesel injector timing and the overall CRDi system.
This is a Genuine OEM Camshaft Position Sensor (CMP Sensor), identified by the General Motors (GM) part number 93310500. This part is the factory-original sensor for the global-market Chevrolet Colorado (and its SUV counterpart, the Trailblazer) built on the RG/S-10 platform during the 2012 to 2013 model years, particularly those equipped with the 2.5L and 2.8L Duramax Diesel engines.
The modern Duramax CRDi engine requires highly accurate feedback to manage its high-pressure fuel system. The sensor performs the following critical function:
Injection Synchronization: It monitors the exact position of the camshaft, ensuring the ECM fires the diesel injectors at the precise moment required for optimal power, efficiency, and emissions control.
Engine Control: The signal is vital for the ECM to synchronize the engine's rotation and ensure smooth operation, especially during starting.
Fitment Assurance: Multiple OE sources confirm 93310500 as the correct Camshaft Position Sensor for the 2012-2013 Chevrolet Colorado equipped with the 2.5L or 2.8L Diesel engine.
Using the Genuine GM Part (93310500) ensures:
High Signal Quality: Crucial for the sensitive, fast-response timing needed by the CRDi diesel fuel system.
Guaranteed Fitment and Durability: Engineered by GM to withstand the harsh heat, vibration, and high-duty cycles of a modern diesel truck engine.
