Heat Pump sensor replacement

[TomServo]

I booked an appointment last week to get the PWS installed. When I took it in yesterday the SA checking me in mentioned my VIN was ID'd as having potential "faulty" Pressure/Temperature Sensors and wanted to replace them as part of a Customer Service Campaign.

Since I took delivery back on July 28th I haven't had ANY issues with the HVAC system and we had temps in the triple digits for a solid week with horrible humidity and temps below ZERO F for a week and the HVAC performed perfectly. Of course, I agreed, he said it would take 3 to 4 hours.

For anyone interested here's a copy of my service receipt:

Hopefully, this is will benefit someone.

Just got my HVAC sensors changed today.

Interesting our part numbers are different.



PS Your info is still visible... Address, Phone number and VIN.

If either of the above 2 cars were mine, I'd request clarification about the differing numbers. Just sayin'.

They are two different parts, 2 on the HIGH aside and 1 on the LOW side.

So strange. I've got VIN 9xxx, and took delivery last June, with no HVAC issues to date here in the mid-Atlantic area, but I'm about to make an appointment to install Homelink, so possibly I'll be getting the same service campaign update. Wonder what part numbers will be used

I had no issues either. Went in for a windshield replacement and they said they'll do this service bulletin at the same time.

Geez...sounds like there may be some impending failure that we don't know about. Mobile tech will be installing my Homelink module next Monday, so I can ask them and see if they'll share any details.

I just had these replaced last week as well. I already had a mobile appointment for a passenger safety restraint alert, and when it got to almost 100 here, the AC would only bring it down to 80 and that's it. I called the service center and they had me bring the car in instead. The AC has been working fine since (knock on wood).

I think this is a pre-emptive replacement of potentially faulty sensors. I received an error code (UI_a006) on my 2021 M3P a couple of weeks ago. I took it in and the same two sensors were replaced. There is a thread about it here.

...and y'all posted 4 different part numbers. I'd still be asking about clarification.

I will contact my SC for clarification. Thanks.

SC advisor just replied to my Phone app message, he assures me the P/N's they installed is the most recent and correct parts for my Model Y.

Thanks for the update. We're all learning about these sensors. It would be nice to have a database of replacement part numbers for reference.

Could you re-post yours? They're not in your original post above.

I needed to redact my PII from the original post, my SA also mentioned they had to fully evacuate the freon and refill it, he said it was 1 pound low from the factory and that can also impact HVAC performance. Which is why they told me it would take 3 to 4 hours and issued a loaner vehicle.

Two of my buddies dropped off their Y's today to have the PWS installed and they were both told they are getting the new sensors.

Here is the Service Bulletin. (SB-21-18-002)

I'll be swinging by the dealer this afternoon to ask about what was used on my car.

 

[Pianewman]

Curious: The Tesla Service Bulletin numbers end in C, your end in B. In traditional auto part jargon, this would imply that YOUR "C" parts are yet another update to the "B" part.

...and Velcade's parts replacement don't match the Service Bulletin numbers. Different sensors?

Thanks, guys, for following up on these important details.

This is why I always find a car forum for each new vehicle. It's good to get this information out there.

 

[Velcade]

Alright, ended up stopping on lunch because I was curious. Talked to the guy and showed him the service bulletin. He said that the March 01, 2021 revision is out dated and the new part numbers are 1581610-00-B for the high pressure sensor and 1581608-00-B for the low pressure sensor.

Is the TSB for all MYs, or a specific VIN range?

I think it's for a range of VINs and you won't know if your MY is affected until you bring it in for service and they tack this onto whatever work you having done.
