Sensor location on Gen III Vortec Truck Engines
LS car have similar locations.
1 – IAC, Idle Air Control
2 - TPS, Throttle Positioning Sensor
3 – Evaporative Canister Purge Valve, (EVAP) Not need remove
4 – Knock Sensor connector, two sensors under intake manifold
5 - Map Sensor, Manifold Absolute Pressure
6 - Water Temperature Sensor
7 - Crankshaft Position Sensor
8 – Camshaft position Sensor
9 - Oil Pressure Sensor.
Not shown here
MAF, Mass Air Flow Sensor, located on the air inlet tube
VSS, Vehicle Speed Sensor, located on Transmission tailshaft
Oxygen Sensors, Vortec has 4, two before the cat and two after. Pre cat O2 sensors will be used others will be deleted
Oil Pan Level sensor, Can be removed as well
