On the gm 5.7l v8 engine vin k where are map and iac sensors located?

On a GM 5.7L V8 engine (VIN K, meaning it's a Vortec engine from a specific year range, likely late 90s to early 2000s), the MAP and IAC sensors are located on the intake manifold, but their precise positions vary slightly depending on the exact year and specific intake manifold design.

* MAP Sensor (Manifold Absolute Pressure Sensor): This is usually located on the intake manifold, often near the throttle body, but sometimes on a more remote part of the manifold. It's a small, round sensor with a single vacuum line connected to it. Look for a single-wire connector.

* IAC Sensor (Idle Air Control Sensor): This is almost always found on the throttle body itself. It's a small, usually cylindrical, sensor located either on the top or side of the throttle body. It often has a single electrical connector attached.

To be certain:

1. Consult a Repair Manual: The best way to pinpoint their location is to consult a repair manual specific to your vehicle's year and model. This manual will have diagrams and pictures showing the exact location of all sensors.

2. Use an Online Parts Diagram: Many online auto parts stores (like AutoZone, Advance Auto Parts, etc.) allow you to select your vehicle's year, make, and model, and then view a diagram of the engine compartment, showing the location of sensors and other components.

3. Visual Inspection: Carefully examine your engine's intake manifold and throttle body. Look for small sensors with vacuum lines (MAP) or electrical connectors (IAC) that match the descriptions above. Be cautious when working around the engine; it's hot when running and there are moving parts.

Remember to always disconnect the negative battery terminal before working on any electrical components.
