need help with numbers, i'm testing my sensors
wondering if anyone had a list of the voltage each sensor puts out, i'm gonna test them all, if you have a how to on each of them i'd love it.
mainly the cts, iac,maf.
i know how to do the tps, any help with these would be great, and yes i did search

The CTS is just a thermistor; I put a table up a while ago with the values. It's the same unit as the MAT (manifold air temp) sensor. The IAC's a stepper motor; I don't know what you'd test on it. I'm not sure what the MAF puts out either; I guess you'd have to test it while the car was running. IIRC, A&C are power, B is the computer output.
But here's the chart (scroll down to see it, I have no idea why it leaves that damn gap, there's nothing wrong with my HTML code!!)
<table BORDER=3 CELLSPACING=3 CELLPADDING=3 >
<tr><td><b>Temp F</b></td><td><b>Temp C</b></td><td><b>Ohms</b></td></tr>
<tr><td>210</td><td>100</td><td>185</td></tr>
<tr><td>160</td><td>70</td><td>450</td></tr>
<tr><td>100</td><td>38</td><td>1,600</td></tr>
<tr><td>70</td><td>20</td><td>3,400</td></tr>
<tr><td>40</td><td>4</td><td>7,500</td></tr>
<tr><td>20</td><td>-7</td><td>13,500</td></tr>
<tr><td>0</td><td>-18</td><td>25,000</td></tr>
<tr><td>-40</td><td>-40</td><td>100,700</td></tr>
</table>
