Issue - O2 sensor voltage at idle + knock sensor

Postby Stoil » Mon Jan 07, 2019 2:16 am

Hi all,

I am building a S13 EUDM with a sr20det black top from a S14 zenki jdm version. ECU Type: WH 23710 75F00
Recently i have installed a new pro wiring harness from wiring specialties. The problems appeared before the wiring installation, so i thought i have a crappy wiring.

Before i install my type 2 board i want to bring the engine to stock settings.
I have a weird problem at idle, the engine O2 sensor is showing values unter 0.2 Volts. Are these values normal? I have been told that the value should be between 0.6 - 0.8 Volts. O2 sensor (thick version) is brand new. (csv attached)

- 1539_30 csv table is driving on first gear inside a garage
- 1507_29 csv table is car idling and standing

I am getting also a fault code 34 knock sensor. My knock sensor is brand new and the wiring to the ecu too. I have checked the wiring for continuity and also the pin numbers.

Could you please help. Thanks. :)
