Who made this AC pressure sensor? What is the part number?

Sun Feb 09, 2020 4:58 am

There is a AC pressure sensor on gen1 Leafs that have heat pump.
This sensor has a different plug compared to those that don't have heat pump capability.
This sensor is sold as a assembly with AC-pipe. No Nissan part number.
All numbers are metric. Thread is also metric (M10x1 AFAIK).

I believe the "D" is the manufacturer's logo and 8610 could be manufacturer's internal part number,
or just detail nr (similar to 12P01).
Other side has plastic formula PPS-GF30. Nothing else has been observed, even with microscope.
Who is manufacturer and on what other vehicles/devices is that sensor used?
This is extremely important for me as the sensor failed :lol:
3-pin, ground-signal-5V. Signal got stuck at 4,9V no matter the pressure. Weight: 23.8grams

Are you not able to find the part via https://parts.nissanusa.com/Nissan_2013 ... /HVAC.html?

I found a pressure sensor at https://parts.nissanusa.com/a/Nissan_20 ... 76A_1.html, specifically https://parts.nissanusa.com/p/Nissan_20 ... 1FA0A.html. Not sure it's right.

As you probably noticed, lots of parts in Nissans come from Calsonic (http://calsonic.com/climate-control-systems). Some sort of merger happened and now they've under the https://www.marelli-corporation.com/en/ brand.

I'm absolutely sure. If you look at the plug you will see 4 external tabs. My sensor has 2.

This applies to part that is on versions WithOUT Heatpump.. aka Visia in EU and S in US.
Aka with 4 external tabs.

Yes it is that bad :?

I'm guessing that the Maxima never had a heat pump, so this is the version for Leafs with heat pump only, apparently. Salvage yards and Ebay dealers may be your only hope(s)...

How much do they want for the "assembly"? You're going to have to evacuate the system anyway...
I noticed you're still working with polymers.

205€ is the part (pipe+sensor).
Actual sensor price should be 25-30€.
For example, BMW 7-series, that costs more than 100 000€ - dealer sells for 60€ - that includes like 40% profit margin.
So no...200€ is absolutely not acceptable.
Salvage Yards is my best bet, but even those sell it as a assembly with gigantic shipping fee.

Replacing the pipe is stupid - instead of 5 minutes of labor it is like 2 hours.
Dealer said: you can throw the pipe away if you want to save on labor costs :lol: What a scam.

Second bet is to get any other sensor (they all work with 3 pins and likely all 5 volts) and get the plug (already asked dealer for that other trim level Leaf plug separately: "not available", no surprise) - I can solder new plug - not sure pressure-signal graph is identical though.

Nobody knows that LOGO?
Maybe run it through image recognition software :geek:

D could be Denso (e.g. https://www.denso.com/global/en/product ... ditioning/) since they italicize their brand name and definitely make automotive HVAC systems. IIRC, my '13 Leaf SV has a reversing valve (for heat pump) from Denso, which is a little unusual given how much Nissan buys from Calsonic.

I don't see any other logical companies at https://www.tokyo-motorshow.com/en/outl ... _list.html.

I think that Cwerdna got it. They likely make the heat pump and this sensor looks like it has a three wire plug/socket:

It isn't identical but they have likely updated it since 2013.
