Your words give the answer "cheaper aftermarket"

They are basically junk that never work. Only use genuine NTK sensors from a bricks and mortar store.

As it is a circuit code, if you are able, I would put a 1amp test light on the circuit just to check that the circuit can carry current. But i think a genuine O2 should do the trick

 

Thanks Phil, that was the issue. I bought a better sensor off of amazon and it worked great!

 

Glad it is fixed for you

OEM/OE all the way, everytime

 

Hi all! 2013 Roadster S here...just got the same code. As I'm looking to DIY this fix myself...I'm not sure which sensor to replace. Looking at carparts.com, I'm seeing "After Catalytic Converter Oxygen Sensor," and "Oxygen Sensor - Replaces OE Number 11-78-7-576-673" and "Driver or Passenger Side Oxygen Sensor" ---don't want to get the wrong one to tend to this P0030 code. Any advice is much appreciated!

 

Can you pull the code as this will tell which one

 

P0030

 

That is the one before the Cat

 

Does that mean downstream (part BS15379) or upstream (BS17187)? Thanks so much for your help with this!

 

that would be upstream of the cat

 

Thanks so much!! Gonna go ahead and order and hopefully replace this weekend! I appreciate the help!

 

No worries, let us know how you get on.

For a heads up, do not but an internet special that is cheap - they are crap and do not react fast enough. This side of teh pond we use genuine NTK from a bricks and mortar place - never had a problem

 

Thanks! I ordered from carparts.com and got Bosch...hoping it is actual Bosch(?). Interestingly enough, the check engine light turned itself off today, a day before the part arrives. I'll see what happens over the next couple of days and if it pops back on and the code is back, I'll replace and report back!

 

good news! the P0030 is gone and that was an easy swap...then the check engine light came back on and current codes are p0597 and 3490. Starting to dig into those and see what's going on. Thanks so much for all of your help in solving my P0030!

 

Glad that one is fixed for you

 

The P0597 and 3490 are the same code. They are an open circuit code for the MAP thermostat, I would start with a visula inspection of the harness from the sensor to the DME and look for damage or green crusties. Yes the sensor is part of teh circuit, but start with the basics
