Error P0140
Asked by Guru123GK Sep 25, 2019 at 10:57 AM about the 2007 Subaru Forester 2.5XT
Question type: Maintenance & Repair
I have a flashing CC light and Solid Cel light.
This has been happening for some time now.
Subaru scanned the car and picked up an error
code P0140. Anyone know where the problem
could be. I have just recently replaced the O2
sensor with a Bosch Universal O2 sensor.
Still getting the flashing CC light and Solid CEL
light.
Thanks

Have you checked your MAF?
No I have not. Subaru said that it was the O2 sensor so I changed that. How can I test the MAF. I assume that is the sensor that you are talking about.?
Well, you can take it out and inspect it to see if it’s contaminated with any dust, dirt or anything like that. You can visually check the prongs on the actual sender to see if there is any corrosion. But to test it, you can test it with an ohms meter and make sure it’s get the right output if any at all.
