Nissan Murano HVAC Pressure Transducers

Nissan Murano Hvac pressure transducers

Starting at $26.95, AutoBuffy stocks 2 HVAC pressure transducers from GPD and UAC. This sensor monitors refrigerant pressure in the A/C system and sends a signal to the PCM to control compressor cycling and cooling fan operation. When it fails, the system loses the data it needs to protect the compressor and deliver cold air.

Signs your Nissan Murano needs a new HVAC pressure transducer

  • A/C compressor clutch refuses to engage even when the system is fully charged with refrigerant
  • Air conditioning blows warm or only slightly cool air despite the blower working normally
  • Compressor cycles on and off rapidly in short bursts rather than holding a steady run cycle
  • Cooling fans fail to ramp up at idle, causing the cabin temperature to creep upward in traffic
  • A/C-related diagnostic trouble codes stored in the PCM, often pointing to an out-of-range pressure signal
  • A/C cuts out intermittently and returns on its own, symptoms worsening in hot weather or at idle

Which HVAC pressure transducer should you buy for your Nissan Murano?

The main decision is whether to match OE specifications exactly or choose an upgraded aftermarket unit. You also need to confirm the sensor location — high-side, low-side, or a combined transducer — because the wrong one will not read the correct pressure range for that port. Thread pitch, connector type, and pressure range must all match your Nissan Murano's system.

OE-Equivalent Replacement
Best for
Drivers who want a like-for-like swap with no calibration changes
What you get
Matches original pressure range, connector, and thread spec; plug-and-play fit with no PCM relearn required
High-Side Transducer
Best for
Replacing the sensor on the high-pressure side of the A/C loop
What you get
Rated for elevated discharge pressures; protects the compressor from over-pressure conditions
Low-Side Transducer
Best for
Replacing the sensor on the suction side of the A/C loop
What you get
Monitors suction pressure to prevent compressor operation when refrigerant charge is too low
Premium / OEM-Brand Transducer
Best for
High-mileage vehicles or repeated sensor failures on the same port
What you get
Tighter pressure tolerance, more durable connector seals, and longer service life than economy-grade units

Replacing an HVAC pressure transducer on a Nissan Murano

Moderate⏱ 30–90 minutesManifold gauge set or refrigerant recovery machine (if port has no Schrader valve)Sensor socket or open-end wrench sized to the transducer hexMultimeter for connector back-probingDielectric grease for connector reassemblyBasic hand tools for accessing the sensor location

Locate the transducer on the high- or low-side line, disconnect the electrical connector, and unthread the sensor using the correct wrench — avoid gripping the body, as the hex fitting is the only safe turning point. Thread in the new transducer snugly by hand first, then wrench-tighten to firm resistance without over-torquing the aluminum fitting. Reconnect the harness, clear any stored codes, and verify A/C operation and correct pressure readings with a gauge set before closing up.

Frequently asked questions

How much does it cost to replace HVAC pressure transducers on a Nissan Murano?
Parts start at $26.95 on AutoBuffy. A shop will typically charge one to two hours of labor on top of the part cost. Because the repair requires recovering and recharging refrigerant, total shop cost rises significantly — doing the sensor swap yourself saves the most money if you have access to recovery equipment.
Can I drive my Nissan Murano with a bad HVAC pressure transducer?
Yes, but the A/C will likely not function, and in some cases the PCM disables the compressor entirely as a protective measure. Driving without working A/C is not dangerous in the short term, but a faulty sensor that allows the compressor to run with low refrigerant can cause expensive compressor damage if left unaddressed.
Will replacing the pressure transducer on my Nissan Murano require a refrigerant recharge?
Not always, but it depends on location. On many Nissan Murano applications the transducer threads into a Schrader-valve port, so refrigerant loss is minimal when swapped quickly. On ports without a valve, a shop must recover refrigerant first. Confirm your specific port style before purchasing so you can plan accordingly.
How do I know if the pressure transducer is the problem and not the compressor or low refrigerant?
Start by checking refrigerant charge with a manifold gauge set — a properly charged system rules out low refrigerant as the cause. Then back-probe the transducer connector with a multimeter; a signal voltage that is stuck at zero, full voltage, or erratic when pressure is stable points directly to a failed transducer rather than a compressor or refrigerant problem.
Are all HVAC pressure transducers on a Nissan Murano the same part?
No. High-side and low-side transducers are calibrated for different pressure ranges and are not interchangeable. Some Nissan Murano applications also use a combination pressure-temperature sensor. Always confirm which port you are replacing — high or low side — and match the part number to that specific location to avoid incorrect pressure readings and continued fault codes.
How long does an HVAC pressure transducer last on a Nissan Murano?
Most pressure transducers last well into the vehicle's service life, but they are susceptible to failure from refrigerant system contamination, moisture intrusion at the connector, and vibration over time. Systems that have experienced a compressor failure or contaminated refrigerant tend to wear sensors faster. Inspecting the connector and wiring during any A/C service is good practice.
