WS2 Flash Codes

Flash Codes

I tested a Honda accord. We located the ECU Diagnostic Plug which was on the front passenger side down by the door. We fused the to pin plug and used a jumper wire to bridge them. Then turn the ignition on and the engine check light started to flash. By watching the engine check light we got code 3, 7 and 10.

By looking in a Manuel we found out what systems had been affected.

Code 3 = Map Sensor

Code 7 = TPS Sensor

Code 10 = IAT Sensor

Now knowing what systems have been affected i did a visual inspection of the engine and found the map, TPS and IAT sensors were unplugged. 

After plugging the affected components back in i cleared the codes by unplugging the negative lead to the battery for about 20 seconds, and then rechecked the codes. No codes came up.

Without these components the ECU wouldn't know whats going on so the cars performance would be very poor.
