P0102 MAF circuit low input.
P0108 MAP sensor high voltage
p0118 ECT sensor circuit high voltage
Freeze Frame Data:
Fuel Sys. 1 CLOSED LOOP
Calc Load % 0.7
ECT Degrees F -39
STFT B1 % -0.7
LTFT B1 % 15.6
MAP [inHg 10.3
Eng. RPM 924
Veh. Speed 0mph
MAF (1b/min) or 7.57 g/sec
TPS % 0
0.240 is that TPS voltage?
What is going on with the vehicle? What are the symptoms you are experiencing?
All three of those codes will show up if you unplug the connectors from those sensors with the ignition on or engine running. Make sure those sensors connectors are plugged in and clear your codes. Then see what codes come back.

You need to answer these questions if you want figure this out.
Did you make sure that all your sensor connectors are plugged in? Did you clear your codes and see if any come back? Did you replace any thing or make any repairs recently?
You had me confused with the 1b/min. I am sure it means lbs/min not 1b/min. If that is the case, .240 lbs/min is equal to 108.7 grams/minute which equals 1.81 grams/second. 1.81 grams/second at 900 rpm is way too low.
