mmaigret Posted August 26, 2020 Report Share Posted August 26, 2020 I recently rewired my sensors, and am now having difficulty getting CAN Lambda working again. I added an ignition-switched relay for the CAN Lambda, as well as the 22uF capacitor, but strangely now when the engine is running I am seeing the Lambda status toggle between diagnostics and calibration, before reporting error 53 controller not found!. It then repeats the cycle with status changing from initializing back to diagnostics. I'm not sure if I damaged the CAN Lambda or O2 sensor somehow during the process, but I've checked all the basics (power, ground, and the CAN setup->CAN Devices in PC-Link appears to find the device) and have not found any obvious issues. Any advice or help would be appreciated. Log file attached. Thanks, Mike lambda issues.llg Quote Link to comment Share on other sites More sharing options...
