Kia Rio 1.5 2001 - Lambda sensor no activity - Fixed #

Posted by Jim Watson on December 8, 2009, 2:02 pm

Year of Manufacture *: 2001
Engine Code or CC *: 1500 A5D
( Optional ) Scanner Used: Launch X431

Hi all, the above car has a code for the "lambda sensor no activity"(sorry left the read out with the customer) which is correct in that at idle and for a great deal of the time the sensor does not switch and is stuck on .25 volts unless I spray carb cleaner into the throttle body however the MAF only puts out at idle 0.15 volts and 0.8 volts at idle which seems too low to me. There are no split hoses or air leaks and idle quality is perfect.

Many thanks Colin, I thought that was a low reading and had no pin data anywhere to confirm, thanks, Jim.
