Failed an emissions test - Power Steering Pressure Sensor P0550
Hey all
I just brought my Z in for an e-test here in Ontario.
It is the new style where they just plug into the OBD instead of the tailpipe. My car threw out this code:
P0550 - Power Steering Pressure Sensor
My CEL is off, so there is nothing wrong. Everything that would indicate a faulty power steering pressure sensor is not present on the vehicle. I have no idea what this has to do with emissions, but I have to get it cleared in order to pass my test.
Unfortunately, it is not just a matter of clearing the code, as the new system they use overrides that (from what I have been told and read on the ministry's website), essentially they force the codes out, so you can't just clear them or disable them to get past the test.
The technician said it is probably just a short in the circuit throwing out the code.
Any solutions, other than replacing the item? It is not exactly a cheap repair, especially given that it may not even solve the problem.
- If anyone in Ontario knows where I can still get a TSI test done then please let me know - I know it will pass the actual emissions just fine.

You can clear the code and see if it stays away for the drive cycle of the vehicle. Anywhere from 10-100 miles depending on your driving. If it comes back that fast then you need to fix the problem.
The reason you can't just clear the codes is because when you clear codes from the system, you have readiness monitors that have to reset themselves.

^ +1. There's a thread somewhere about the Nissan Drivecycle Procedure, but otherwise if you drive it for a couple hundred miles it should be ready. Not sure how it works in Canada, but over where I'm at I get the testing place to check if my readiness codes are ready before I pay for an inspection.

You would have to have the readiness monitors checked, some scanners can grab the code (eg. ones at emissions testing stations and approved places), but the normal CEL reader/autozone reader won't be able to tell.
