P0030 code

Postby cameron griffith » Wed May 03, 2017 7:12 pm

So the CEL and cruise control was flashing, found out it was the O2 sensor so I purchased a new pre-cat oxygen sensor

The code is still P0030. Any help on where I can go for here?

Did you reset the ECU?

Did the CEL go off at least for any length of time?

Do you have a multimeter ?

Apparently you can test:
"You can check the heater for continuity between pins 3 & 4 on the connector. It should be about 5 ohms."

Quoted from here :
http://www.subaruforester.org/vbulletin ... 523?page=1


The ebay ad also mentions how to test if the O2 sensor you bought even works.

I'm guessing they mention that because they get a lot of returns.

Likely a cheaper sensor and not of good quality, possibly DOA.

The ECU got reset and the CEL stayed off until I took it for drive around the block. I've tested it with a multi meter and it looks like it's also a faulty O2 sensor cos I am getting 0 ohms so I'm going to return it.

Is there any other option than buying one from subaru as I don't want to spend a ton :lol:
