Post by lancia58 »

Hi

Using the Lexia for engine diagnosis I found the following filed : Can. valve OCR . Does anyone know what does it mean ? What should be the readings ?

Thanks

Do you mean cannister valve OCR ? The OCR (open cyclic ratio) is the duration that the component is switched on or opened for. The reading varies depending on lots of different vairiables like engine speed etc. This is assuming you mean the charcoal cannister electrovalve.
