Please helpppppppppppppppp. Please help
HI, I HAVE 98 CORVETTE CONVERTIBLE..
I HAVE A BIG PROBLEM, MY MECHANIC COULD NOT FING THE BIG PROBLEM..
MY MECHANIC SAYIND THE -- IAT(Intake Air Temperature) SENSOR AND THE ECT(Engine Coolant Temperature) SENSOR IS SHOWING IN THE SCANNER -40 DEGREE,AND THIS IS NOT RIGHT..
please help me,, my car is in the mechanic for 2 months and time cost money...

Joe,
Get the car back, those two items should then need replacing are very simple to replace. What is the car doing and why would it take him that long to replace such simple parts?

Very simple really. Your computer is not receiving data from the new sensors ! Could be a loose connection,wire pulled out,wire pinched/cut or faulty computer(unlikely) Start with the ECT,its easiest,trace the circuit(two wire) from the sensor on the dr cylinder head front,to the plug on the computer.Once that is fixed,you can attack the IAT. Follow precisely the trouble tree/repair track using GM approved procedures and you will not have any problems.

Well, looking at the schematic posted here the problem is one of 2 things. The 5V is not being applied to one side of the sensors, or the ground sides of the sensors are not connected. I would follow the 5V feed to the fuse. I'll bet the fuse is blown, or not installed.
Have him measure the 5V side of each wire in each connector and verify if the voltage is there. Put one probe of the meter into the connector, then the other to a ground point. If you see voltage, then put the meter into each pin of the connector. If you measure voltage, then the part is bad.

IMO its the wires near the connectors that can fail with both of these sensors. The replacement connectors have pretty long wires with them, just have them splice the new connectors in and keep the new wires pretty long. The connectors are pretty cheap, and it won't take long to do. I'd do that before spending more money trying to trace the wires, especially since it sounds like the mechanic is not familiar with C5s.

Guys the OP has only been here since March, we all F-up the rules sometimes, maybe ease up a little. I'm sure he is frustrated is all.
To the OP, hang in there dude, you are getting some good advice. You probably need another mechanic IMO.
Best of luck

but everything you guys it wroted he ready did before he make double check, he told me..
the computer sending messager for the sensors but the sensors is not send back..
the question it, is possible the problem is the pcm????

You need to go to a shop that has a Tech II. This should be a real simple fix.

Just be aware that some dealerships (like some repair shops) keep installing expensive parts on a car until the problem is fixed.
And, to add insult to injury, even if the problem is NOT resolved because of their incompetence in diagnosing, you still pay for their “hit and miss” experimenting.
Sometimes a problem with a component like the PCM is actually with the electrical connections (their plug-in terminals) because of poor (corroded) connectors and NOT the component itself.
I shudder at the thought of how many EXPENSIVE electrical components are replaced that are in good working condition.
