Code PS173, vacuum leak?

Hi,

As far as locating a vacuum leak is concerned, here is a link that explains how to check:

As far as the code is concerned, usually, they start with P0. I suspect that was a typo, but when I checked for a P0173, it wasn't listed for this model.

Could you confirm the code for me?

Let me know.

Hi,

That works. LOL The code is related to a large vacuum leak. If in fact it is a leak, you will be able to find it using the link I attached above.

On the other hand, if there are no leaks found, then suspect it could be a few things. For example, a faulty MAP sensor, wiring issues, the PCM itself, or even the throttle body.

I attached diagnostics below specific to the code. Take a look through them and let me know if you are comfortable performing them.

Take care,

Joe
