??? Why would he clear the codes without pulling them first ?

Fwiw. Dump the HF code reader and get something else. I use the Torque app with my phone for reading codes. All of about $35 for the app and the wireless OBD port plug.

 

Well anyway, since your guy did you the favor of clearing the codes, you will now be surprised when the CEL returns in about 2 weeks, after ALL of the OBDII monitors run. It takes about 17 "COLD start to Warm up cycles" with the right combination of fuel level and run time for the EVAP monitor to get triggered.

Sure would have been easier to just get the codes! Most likely if you had re-read the HF OBD reader manual (ReadTheFlippenManual) you would be ready to go now.

The HF tools I've seen are of "fair" quality for the shade tree mechanic, but you must to read the description; in this case OBDII with CAN. Then read the manual.

If you just don't want to look at the CEL for a while, just pop the negative connection on the battery (in the trunk) off for a couple of minutes. That WILL NOT fix anything, but the light will stay off for a while.

 

Like I said in post #2, but what do I know! It could have been many things caused the codes like loose fuse box halves or loose ground wires , faulty gas cap, evap valve, forgot to plug in the MAF sensor.......
