Hello intelligent guruz... I use Honda accord 2000 v4....so.. I was playing with my car scanner and I got these data I can't really Inteprete thou I try to learn from this house... Please guruz.. Help interprete these data... Pics below.. Cc..gazzuzz, mayor123, nurey, honmusa, obiekemondautos, cardoctor, timifakay, autologic, chukel, kingreign, egunmojaji, and other guruz... Thanks house.. ... NB...i used torque pro

There are terms like timing advance.. I don't know what it means.. Also.. Terms like throttle position.. Intake psi.. And lots more.. I need to know please.. Below are screenshots of more live data and freeze frame data obtained using piston app.. Thanks for your anticipated input..

Please guruz.. Help analyse the values of my 02 sensors.. I scanned a friends car and his values were above 1%..but mine are below 1%.. |

captainking: To get fault codes: Press that circle by the lower left then press fault codes on the list that follows. That's when you vehicle will be scanned for DTCs |

Mayor2013 and costee. Are you there... |
Re: Car Guruz.. Please Help Interprete These Data.. by captainking(m): 8:08pm On Nov 01, 2017 |
timifakay:i scanned it and it threw a code... Thou I know the codes ain't complete cos I cleared it days ago and haven't driven the car since then for it to throw back the codes.. But all the codes it threw were oxygen sensor related.. It threw about 2 codes.. |

Some gurus here na olodo. They can't interpret real time data. They can only Google search Cel and ecu stored codes. Lol... Don't expect much response on this thread. Them go dodge the thread like the plague. 1 Like |

No analysis can be made here cos this is a set static data at a particular instance or condition. The conditions need to be varied to make analytical sense out of the whole array of dynamic data eg idle condition ,acceleration, deceleration, addition of fuel ,removal of fuel etc . Beside it is only the set of scandata pid that is relevant to the issue suspected that the focus will be not some random pid and who determine what pid the spotlight will be on is the technicians that is involve in troubleshooting and the capability of the scan tool to give out the needed pid ! Since the op alreay made mention of O2 sensor issue them the set of pid that the focus will be should be the fuel trims(O value) ! Fuel system type (absent) ,fuel injection (absent) etc . I advice that you make use of professional scan tool |
Re: Car Guruz.. Please Help Interprete These Data.. by mayor2013: 10:24pm On Nov 01, 2017 |
Would advice if you want real actual values use a professional scan tool. I can't even see values for LTFT(long term fuel trim) and STFT (short term fuel trim) |

Try and find out the required temperature your car should be. I think 85 degrees should be the temp when fully warmed, so your 70 degrees is number one suspect before oxygen sensor. Change thermostat first and if it still doesn’t work then change engine coolant temperature sensor or if you have the money just change both at once. When I changed mine there was a very big difference in MPG, also clean your MAF sensor thoroughly, find YouTube videos on how to thoroughly clean a MAF. As for your fuel trims, the only way to know if they are working and not just static is to raise your RPM at 1500 and 2500 to see if your STFT will change, it should change under normal circumstances because you are adding load by raising your RPM. I hope I have been able to help in my little understanding since I’m not a mechanic. OP Make I borrow small space from your thread, does any car guru in the house know much about in tank fuel filter for Toyota engine 1AZ-FE, some say I don’t ever need to change it which I doubt. I need help on this as I read this could cause engine lean condition. 1 Like |

there is only one person I know who can read and interprete live data....... cc honmusa 1 Im a diy guy with experience in very few brands.... Toyota inclusive 2 its not obiekediamondautos Lolz, check again. 3 I'm not really into Honda but nonetheless, ur car hasn't reached optimu. temp from the readings, ur ignition timing advance is OK considering ur car is at idle, The following are known good voltages for air-fuel sensors compiled over the last few years: 3.3 V (Toyota), 2.8 V (Honda), 1.9 V (Hyundai), 2.44 V (Subaru), 1.47 V (Nissan), after vehicle has reached operating temp. don't bother too much about ignition timing, its. complicated to understand than to set. it simply is the timing of the spark in the combustion chamber for efficiency..... when the spark is introduced just before the piston reaches top dead center so that it can comp!etely burn the fuel inside. the concept is still dicey to me but It easier to set. since ur o2 sensors are generating volts I think the pid would indicate that the volts are below spec also u need to move the vehicle around for like 50blocks to generate stft and ltft |

olaboy1: u probably don't need to change it, it is a serviceable part. but don't go running on reserve always cos it will clog it and in turn the pump and the ripple effect goes on to the injectors. also hope the vehicle is not so old cos we tend to overdo things.. 1 Like |

You were playing with your scanner, so you are inviting us to come play with you? Well, let me finish my home work first. But really, nothing to interpret. Your scanner is DIY, and there is no specified diagnostic target. |
Re: Car Guruz.. Please Help Interprete These Data.. by ZIMDRILL(m): 7:25am On Nov 02, 2017 |
you are being lazy to do simple analysis most are self explanatory eg throttle position was 10% measurement goes to last digit which 100% revs you should know if you dont stop driving coolant/water temperature etc those measurement are useless are you are comparing them with manufactures data or data from part manufacturer as for 02 sensor number no two cars can have the same exact readings even when the part is working fine why are you comparing your friends reading and yours ? 1 Like |

Op...I'm also a DIY guy, but I think these readings are self explanatory...regarding your STFT(Short fuel trim), it should fluctuate between +/- 10...when you get double digits, there's a problem...the positive readings posit a rich mixture, while the negative reading connotes a lean mixture...you should note that the LTFT...(Long fuel trim) is what the ecm saves over time, from the readings of the short fuel trim..(STFT)...during a lean mixture, the ecm tells the engine to pour in more fuel for optimum combustion, while, during a rich mixture, fuel is reduced...also note that, the readings from the 02(oxygen) sensors are responsible for the STFT and LTFT...on a 14:7:1 ratio..(air/fuel ratio)...there's so much to explain here...besides your vehicle is on idle...drive and monitor how your o2 sensors flunctuate, as well as your STFT and LTFT...via 'Live data' on your scanner and post pictures. 1 Like |
Re: Car Guruz.. Please Help Interprete These Data.. by Alvin007: 10:51am On Nov 02, 2017 |
Op...regarding the pics of the o2 sensor readings you posted here...it looks ok...provided the downstream o2 sensor(o2 sensor 2) doesn't switch readings as frequently as the o2 sensor 1(exhaust manifold sensor)..in the case of your car...while on idle..it's normal for both of them to switch readings intermittently while your vehicle moves...but, on idle, the downstream sensor should change less frequently, while the sensor 1 switches more often... If both switch at the same rate while your car is on idle, it means you have a catalyst issue..I'm not sure your car uses a mass air flow sensor. 1 Like |
