Hey Mike in case you do the write-up this could be helpful.ĮMF - electromotive force (generated voltage)

Knock sensor signal (open or short in knock sensor signal): knock sensor/circuit ECUĮGR valve malfunction (exhaust gas tempeature below specification for EGR control): EGR system EGR gas temperature sensor/circuitĪir conditioner compressor relay/relay signal: A/C compressor relay/circuit ECU Switch signals: TPS idle switch off neutral start switch off (automatic transmission in Drive) A/C switch on A/C switch/circuit A/C amplifier TPS/circuit neutral start switch/circuit ECU Starter signal (no "sta" signal to ecu until engine speed exceeds 800rpm): vehicle is push started ignition switch/circuit ECU. Vehicle speed sensor signal circuit (no speed signal for several seconds): while vehicle is operated under heavy load (tps/map/air flow inputs) speed sensor/circuit ECU Throttle position sensor signal: open or short in tps signal tps sensor tps signal/circuit ECU Turbocharger pressure sensor signal: turbocharger pressure sensor ECU Manifold and/or airflow meter sensor signal circuit: airflow meter/circuit manifold pressure sensor/circuit ECUĪirflow meter signal (vane-type): airflow meter/circuit ECUĪbnormal turbocharger pressure: turbo charger airflow meter/manifold/turbocharger pressure sensor intercooler system ECU #2 oxygen sensor/oxygen sensor heater same as code 21 Sub-oxygen sensor circuit or sub-oxygen sensor heater circuit ECU Try cleaning the injectors.Īir/fuel ratio rich indicator: same as 25 cold start injector Intake air temperature sensor signal: open or short in intake air temperature signal intake air temperature circuit intake air temperature sensor ECUĪir/fuel ratio lean indicator (lean signal sent to ECU from oxygen sensor): injector fault(s) injector circuit injector oxygen sensor circuit oxygen sensor air leak fuel pressure line airflow meter or map sensor ECU. Water temperature sensor signal (open or short in water temperature sensor signal): water temperature sensor circuit water temperature sensor fault in coolant temperature sensor circuit ECU Oxygen Sensor signal/oxygen sensor heater signal: open/short in oxygen sensor or signal Ignition signal (no "igf" signal to ecu, no signal from igniter 4 times in a row): igniter/igniter circuit igniter and ignition coil/circuit ECU Same as 12 but after engine has run at 1,000-1,500 rpm: distributor/distributor circuit ECU RPM signal/no-signal to ecu from distributor ("ne" or "g") after engine has been cranked: distributor/circuit starter/signal circuit igniter/igniter circuit ECU Loss of power to ECU: ignition switch/circuit main relay/circuit ECU
