JF010E JF011E CVT Pressure Sensor

The JF010E JF011E CVT Pressure Sensor is a threaded hydraulic pressure sensor used in selected Jatco continuously variable transmissions. JF010E is commonly associated with the RE0F09A / RE0F09B family, while JF011E is commonly identified as RE0F10A. Professional transmission catalogs cross-reference this sensor under industry number 203414A and list it for primary and secondary pressure-monitoring applications depending on the transmission configuration.

The sensor converts hydraulic pressure inside the CVT into an electrical signal for the transmission control system. Unlike a simple on/off pressure switch, this type of pressure sensor is used to provide pressure feedback so the TCM can evaluate whether the hydraulic system is operating within the expected range.

This product is intended for professional transmission workshops, valve-body rebuilders, CVT specialists, distributors and wholesalers.

JF010E JF011E CVT Pressure Sensor Function

The JF010E JF011E CVT Pressure Sensor monitors hydraulic pressure inside the transmission. CVT operation depends heavily on accurately controlled fluid pressure because the hydraulic system is responsible for pulley clamping force, clutch or brake operation, lubrication and ratio control.

The pressure sensor sends information back to the transmission control module, allowing the TCM to compare actual hydraulic conditions with commanded values.

If pressure feedback is incorrect, unstable or missing, the transmission may store diagnostic trouble codes or operate in a protective mode. However, pressure-related faults do not always indicate a failed sensor.

Possible alternative causes include:

• Oil pump wear
• Valve-body leakage
• Pressure-regulator problems
• Damaged wiring
• Connector faults
• Contaminated CVT fluid
• Internal hydraulic leakage

Professional diagnosis should therefore be performed before replacing the sensor.

203414A Industry Reference

The industry reference 203414A is widely used for this Jatco CVT pressure sensor family.

WIT identifies 203414A as a black three-prong pressure sensor used for RE0F09A/F09B secondary pressure and also for primary-pressure applications. The same sensor is also listed for RE0F10A / RE0F10B JF011E primary and secondary pressure sensing.

Other transmission catalogs similarly list 203414A-EM as an OEM pressure sensor for JF010E / JF011E applications.

This makes 203414A a much better product reference for your page than using a guessed Nissan OE number.

For your website, I recommend:

Industry Reference: 203414A

rather than:

Nissan OE: 203414A

Primary and Secondary Pressure Applications

One important feature of this sensor family is that it can appear in more than one hydraulic pressure position depending on the transmission.

For JF011E / RE0F10A, professional catalogs list the same sensor family for both primary and secondary pressure monitoring.

That means your product page should avoid saying:

“Only Primary Pressure Sensor”

or:

“Only Secondary Pressure Sensor”

unless the specific installation location is known.

The safest wording is:

Primary / Secondary CVT Pressure Sensor depending on transmission application.

This also explains why suppliers often sell the same physical sensor under broader JF010E/JF011E application listings.

Pressure Sensor vs Pressure Switch

Your photo is important here.

The component has a threaded metal pressure port, a large hexagonal body and an electrical connector. Combined with the catalog information for 203414A, this matches a pressure sensor rather than the simpler switch terminology sometimes used in aftermarket listings.

Some suppliers still loosely call the JF011E part a “pressure switch,” especially in older catalog descriptions. Mid-Mountain, for example, describes 203414A as fitting JF011E primary and secondary “switch” positions, while its detailed description still identifies the component itself as a pressure sensor.

For an English B2B website, CVT Pressure Sensor is the clearer and more technically accurate product name.

JF010E and JF011E Application Matching

JF010E and JF011E are related Jatco CVT families, but they are not the same transmission.

JF010E is commonly associated with RE0F09A / RE0F09B applications, while JF011E corresponds to RE0F10A.

Because the same pressure-sensor family can appear in several applications, customers should still confirm the original sensor design and connector before ordering.

Useful matching information includes:

• Transmission model
• Original sensor photo
• Connector pin count
• Thread size
• Any printed number
• Valve-body or case installation location
• Required quantity

Professional CVT Repair

Before installing the JF010E JF011E CVT Pressure Sensor, technicians should inspect the electrical connector, wiring and hydraulic mounting port.

The transmission fluid should also be checked for contamination. If the transmission has low actual hydraulic pressure, replacing the sensor alone will not correct a worn pump, leaking valve body or damaged pulley-pressure circuit.

The sensor should be installed using correct torque and sealing procedures appropriate to the transmission.

After replacement, diagnostic fault codes should be checked and cleared as required, and pressure-related data should be verified using suitable diagnostic equipment.
