mindflux Posted June 25, 2004 Share Posted June 25, 2004 Hey, I just did my 02 Sensor Test, This is how i did it.. Set my ECU into test mode warmed the car for about 5 mins (till it dropped to 800rpm) then i held my foot on the accelerate till 2 grans held it there for 10 seconds then released. in this time the ecu light flashed about 5 - 7 times in about 10 seconds (not accutarly) But then it was kinda flashing all over the place, like after that it went off for abotu 10 seconds then stayd on for about 20 an yeah im nto sure what all this means. I heard if it flashes between 5 - 10 in 1- seconds, this is normal yet ive heard if the light stays on its running lean but if it stays off its running rich. In my case it did both of this :S Anyone able to help me understand? Link to comment https://www.sau.com.au/forums/topic/44392-02-sensor-test/ Share on other sites More sharing options...
paulr33 Posted June 25, 2004 Share Posted June 25, 2004 the only way to test if the 02 sensor is dead that i know of is to remove it (its on the exhaust manifold) and shake it. if it rattles its dead. its only supposed to last 40,000ks. if its dead youll have terrible fuel economy. its been done in the maitenance section probably 10 times in the last month, check out the thread "o2 sensor". i had bad fuel economy and ive done 40,000 ks since ive had my car and its never been changed so i took the plunge and changed it ($117 part) and my fuel economy increased by about 100ks on a full tank Link to comment https://www.sau.com.au/forums/topic/44392-02-sensor-test/#findComment-907849 Share on other sites More sharing options...
mindflux Posted June 25, 2004 Author Share Posted June 25, 2004 Awsome bro, ill look in to that.. I was just trying to understand what these flashes and that represent?

paulr33 Posted June 25, 2004 Share Posted June 25, 2004 no problems. ive never done ecu diag so not sure what its like but it sounds very confusing thats for sure. theres a guy who made a consult hack up to an lcd display which shows all the stock ecu sensors for about $300 which could be handy, its in the for sale section. it shows the o2 sensor Link to comment https://www.sau.com.au/forums/topic/44392-02-sensor-test/#findComment-907917 Share on other sites More sharing options...
mindflux Posted June 25, 2004 Author Share Posted June 25, 2004 ECU check is a piece of piss. even i could understand it But this 02 sensor has got me a bit confused.. ill have a look at the forsale section thanks mate Link to comment https://www.sau.com.au/forums/topic/44392-02-sensor-test/#findComment-907922 Share on other sites More sharing options...
Penfold Posted June 26, 2004 Share Posted June 26, 2004 Can't recommend the NissDatascan enough. Installed one on my GTR Friday ( by installed I mean I plugged it into the consult port) & works very well. Displays 8 engine parameters on the screen out of - RPM - AFM voltage (2 for my GTR) - Speed [miles/kph] - Injector Pulse Width - Injector Duty Cycle (%) - Water/Coolant Temp Sensor (°C & F) - Ignition timing - Throttle Position (voltage & %) - 02 sensor (voltage, + lean/rich) - AAC Valve position (%) - Battery Voltage - Flags (a/c compresser on?, Power steering pump on?, Neutral Gear Selected?, Closed TPS) - More Flags (A/C Relay on?, Fuel Pump on?, VCT Solenoid on?, Termo fans on?) - More Flags (P/reg on?, Wastegate valve on?, IACV-FICD on ?, Egr on? Hence you can diagnose most problems straight away. Saves dropping into mechanic & having them tinker around & recommend replacement parts. I'll take a few photos tomorrow & do up a review when I get hold of a laptop to test the logging. Otherwise just by one from the wreckers if your pretty sure its broken - there not that expensive.

Sounds good to me.. Something is suss when it comes to my ECU. I have an RSM which reads my information incorrectly. I also have a type one timer which also reads my revs/speed incorrectly. I dont know if the timer if piggy backing off the rsm wires or what?

yogi000 Posted June 27, 2004 Share Posted June 27, 2004 what type of turbo timer is it??? Link to comment https://www.sau.com.au/forums/topic/44392-02-sensor-test/#findComment-910111 Share on other sites More sharing options...
mindflux Posted June 27, 2004 Author Share Posted June 27, 2004 HKS type 1? its the blue screen one, 99.9% sure its type 1 there a port near the fuse box .. is there anyway i can use my lap top to read my ecu via this port?

yogi000 Posted June 27, 2004 Share Posted June 27, 2004 I got the same one, and if you used the diagram in the manual to hook it up to the ECU, its wrong. The manual shows the wrong pins to connect the Speed & Revs, thats from personal experience.

mindflux Posted June 27, 2004 Author Share Posted June 27, 2004 Ohh.. i got mine from japan so i translated the instuctions .. let me look at my translation, brb Link to comment https://www.sau.com.au/forums/topic/44392-02-sensor-test/#findComment-910200 Share on other sites More sharing options...
mindflux Posted June 27, 2004 Author Share Posted June 27, 2004 Ok, I dont know where its connected to on the ECU but this is what my translation says red - battery positive blue/brown - ign 1 green - ignition black - earth brown - revs I didnt install it and thats the translation someone did for me although looking at it now, it doesnt seem to soudn right like its missing some wires or something Link to comment https://www.sau.com.au/forums/topic/44392-02-sensor-test/#findComment-910210 Share on other sites More sharing options...
yogi000 Posted June 27, 2004 Share Posted June 27, 2004 I got the english manual here, i also got mine from japan too and the diagram of the ecu in the manual is wrong or it could be havent calibrated the revs and speed yet. Red - 12 volt constant Green - 12 Volt Ignition Blue - 12 vold accessory Gray - Handnbrake Brown - RPM Blue - Speed Link to comment https://www.sau.com.au/forums/topic/44392-02-sensor-test/#findComment-910221 Share on other sites More sharing options...
mindflux Posted June 27, 2004 Author Share Posted June 27, 2004 I know nothing about wiring, but ill take a look tomorrow and see what i can find. i have a feeling its piggy backing the wires to my RSM and my rsm isnt wired up correctly Link to comment https://www.sau.com.au/forums/topic/44392-02-sensor-test/#findComment-910231 Share on other sites More sharing options...
