Note On INTERMITTENTS
If intermittent code is being set, observe engine data parameter P.1.0. This reading is monitored off the fuel pump feedback input (circuit No. 120) that is also used to set code "E16". If code is being set due to high current draw in a certain vehicle component, this effect can be observed reading parameter P.1.0. Operate various components while watching for reading to drop below 10.5 volts. This will help isolate location of malfunction.
