IAT & CTS Sensor

can someone please help me find the Intake Air Temperature Sensor and the Coolant Temperature Sensor???? Not the O2 Sensor!! If you could either talk me to where it is, or post a picture pointing to it, that would really help me!! Thanks!!!

IAT is integrated within the MAF module assembly................easier to download FSM to find locations of all sensors.

Performance Chip

I have this performance chip that I'm supposed to attach to the Coolant Temperature Sensor which in turn will send a different signal to the ECU. What are you thoughts about it, do you think it will harm the engine?

Fooling ecu signals into thinking ambient conditions are different than they are can change the AF ration and sometimes ignition advance.

Modern ecu are tuned so closer to limit than pre OBD2 ecu...........not much upside and potential MPG and durability/longevity downsides.
