Code reader assistance
He wants one that will read OBD-II system also and give more information than just codes.
The CP9190 will do all of that and here is an example of the extra information.

/
CANST PURGE =
On the solenoid is on and passing gas vapor to the intake.
Off the solenoid is closed and does not pass gas vapor to the intake.
ECT(V) = The voltage the engine temp sensor is sending back to the computer.
ECT(øF) = The temp the computer takes the above voltage to be in Fahrenheit. Can also display in Centigrade.
ENGINE SPD = The engine rpm when the readings are taken.
EVP(V) = The voltage the EGR position sensor is sending back to the computer.
EVP(%) = The percent the computer thinks the EGR valve is open.
FUELPW1(mS) 5.5 = The time the fuel injector is on in mS.
IAC(%) 38 = The percent the computer thinks the IAC valve is open.
IAT(V) 2.8 = The voltage the IAT sensor is sending back to the computer.
IAT(øF) 82 = The temp the computer takes the above voltage to be in Fahrenheit. Can also display in Centigrade.
LOOP STATUS Open = The computer is in open or closed loop.
O2SEN 1(V) 0.10 = The voltage the O2 sensor is sending back to the computer.
SPARK(ø) 24 = Spark advance from base timing in degrees.
ST FTRM1(%) 8 = Short-term Fuel Trim calculated value that has a positive percentage is a rich fuel trim and if a negative percentage is present the fuel trim is lean.
TOT(V) 2.6 = The voltage the TOT sensor is sending back to the computer.
TOT(øF) 88 = The temp the computer takes the above voltage to be in Fahrenheit. Can also display in Centigrade.
TP MODE C/T = The mode the computer thinks the Throttle Position sensor is in. There are three modes for the Throttle Position sensor, they are C/T-CLOSED THROTTLE, P/T-PART THROTTLE & O/T-WIDE OPEN THROTTLE.
TPS(V) 0.8 = The voltage the TPS sensor is sending back to the computer.
VPWR(V) 14.3 = The battery voltage that the computer is seeing.
VREF(V) 5.0 = The voltage the Voltage Regulator in the computer is putting out.
VSS(MPH) 0 = How fast the computer thinks you are going in MPH.
