Return of the Jimny OBD faults.....
For those of you who recall my problems with my cousins Jimny....the engine check light came on, she took it to the Suzuki dealer, they charged her
£45 plus vat to tell her it needed a new O2 sensor and the new one would be £145 plus vat, then £45 plus vat to fit it, then another £45 plus.... to
reset the fault codes. Well I bought the OBD2 reader, fitted a new sensor and two miles up the road, the engine check light came on again...........
With P0134. It reset OK. but two days later the light returned.
I got a call from her yesterday to say that the car had broken down on the M18. "The rev counter went nuts and the car was shuddering".
This time, I'm getting P0171 and P0134. This is 'System Too Lean (Bank 1)'
and '02 Sensor Circuit No Activity Detected (Bank I Sensor 1)'.
I trundled off to collect her and the Jinmy, and whilst driving back up the M1 (a horrible experience in a Jimny!!), the O2 sensor was reading all
over the place!! At a steady 60mph without moving the throttle, it was wandering anywhere from 0v upto 0.050V. Every now and again, it would stop
reading anything and the P0134 would ping up. Then it would eventually ping up the P0171. The car feels shuggish but according to Rebecca, it always
has......
Any suggestions? I'm thinking of cleaning the MAF when I get chance as at the moment, the car seems to be going OK so it's being used.
Cheers in advance!

Dodgy earth somewhere perhaps?
I had issues with my ABS pump... turns out the earth wire connectors were a little bit dirty

Yes. I bought one and fitted it. Then two miles up the road, a new fault popped up!
The original fault, when the main stealer was involved, was before Christmas but Rebecca was just ignoring the light!

The upstream O2 sensor should read all over the place, it should flicker several times a second between about 0.1 volt and 0.8 it should average
somewhere i the middle.
You know an upstream O2 sensor is dead if it give continuous voltage readings or only changes very slowly.
In constrast the downstream sensor (ie post cat) should give very steady readings.
In this case the fault sounds very much like a connection issue.

This feckin roller skate is having my eyes out!!!! How hard can it be!!
The O2 is reading between 0.1 and 0.9 whilst sat ticking over which is OK so why is it still pinging the blumin P0134, Circuit No Activity Detected
Sensor 1 thing???
Give me strength. Or a box of matches....

Having had a read on the greatist source of mis-information, the tweb, one site suggests that if the ECU doesn't see at leaST 0.45 volts, then
the ecu will ping the P0134. Does that sound right?

For if anyone is still bothered.......
I took the Jimny for MOT this morning and it failed on emissions which was no suprise!
A mate had a few old O2 sensors out of a bundle of Chrysler Neons that he'd scrapped so I cut the plug off the end, pondered what each wire did,
fitted the sensor to the Jimny, poked the wires into the connector block and the car has been fine! The O2 was very good for the MOT. The car drives
better than it ever has and the MIL light has stayed inside the ECU.
So after all the trouble, which did stem from a faulty sensor, the problem was with the replacement. Gendan, who supplied the sensor have been very
helpful with advise and things to try but everything I have done, including checking all the wires back to the ECU, checking every earthing point,
multi connector etc, has pointed to a faulty sensor, which Gendan say, doesn't happen.....
Lets see what they say now!!!

Isnt it sods law that you do someone a favour and end up with a nightmare on your hands.
Pleased you seem to have it sussed. Its too easy to discount new bits that have been fitted, but how many would have suspected a new 02 sensor to be
faulty?

It would have been cheaper and quicker to stump-up the £150 for the genuine suzuki part!! It's a good job it only take 30 seconds to change the
damn thing.
once you've spent half an hour trying to open the bonnet....
