Clubspectom Posted April 14, 2020 Report Share Posted April 14, 2020 Hi guys, noticed my lambda readings in PCLink made no sense whatsoever, i.e 3.5 at idle! The cars started running super rich based on smell and high fuel usage, so I took it to my tuner to check with his dyno sensor. He was away today, so I just checked with one of the general mechanics and it was sitting at 1.3 lambda at idle, and jumped to 0.7 at 2000rpm. I assumed the sensor was rooted a few days ago, so ordered a Bosch 0 258 017 025. Can anyone confirm if this unit is plug and play with the Link CAN lambda kit? https://www.bosch-motorsport-shop.com.au/lsu-4.9-oxygen-sensor~4260 Also, would the faulty sensor make PCLink show an odd lambda value (see attached photo)?

Clubspectom Posted April 20, 2020 Author Report Share Posted April 20, 2020 I can confirm the Bosch 0 258 017 025 was plug and play. I can also confirm that my original sensor was rooted - once changed for a new sensor the lambda reading went back to an acceptable range.

Gsab Posted October 20, 2020 Report Share Posted October 20, 2020 Hiya, was your 017 025 sensor a 5 or 6 wire ? Missing the green wire ? I see this is the trimming resistor, how super critical is that ? Quote Link to comment Share on other sites More sharing options...
