Where is pressure switch - Cars & Trucks

1. locate the oil pressure switch: The oil pressure switch is usually located near the oil filter or on the engine block, close to the oil pressure gauge sender.
2. Check for oil leaks: Look for any visible oil leaks around the oil pressure switch and its connecting hose. If you see any oil leaks, it could indicate a faulty oil pressure switch.
3. Check the oil level: Check the oil level in the engine and look for any signs of a decrease in oil level, which could be a sign of an oil leak.
4. Listen for any unusual noises: If you hear any unusual noises coming from the engine, such as a hissing or whistling sound, it could indicate a leak in the oil pressure switch.
5. Monitor the oil pressure gauge: If the oil pressure gauge is reading low or fluctuating, it could also indicate a problem with the oil pressure switch.

If you suspect that the oil pressure switch is leaking oil, it is best to have the vehicle inspected by a certified mechanic or a Hyundai dealership

I believe that is the. Oil pressure switch code. Majority of the time it is the oil pressure switch going bad. If you have the v6 3.1 or 3.4 it is located on the front of the engine right above the starter.

The high pressure runs in the smaller diameter tube.

Thread the new switch into the block by hand and then tighten the switch securely with the the oil pressure switch socket. Connect the electrical wire to the new oil pressure switch. Start the vehicle and check for oil leaks at the oil pressure switch. Verify the operation of the oil pressure gauge.

If we are talking about a pressure switch, it usually is the low pressure cut-off switch. Before messing with this switch, verify what your Freon pressure is.
If the pressure is low, the low pressure switch may be fine and you need to add Freon and find out why the Freon escaped.
If you have high pressure, there is a second switch which cuts power to the compressor. Too much Freon will activate this switch.
Tip: You have both a high and low pressure switch. The proper amount of Freon will center the pressure and keep the compressor running more consistently.
Either pressure switch unscrews from the fitting and with a minimum of pressure can be removed from the lines and replaced. The housing should have shapes for wrenches.

P1782 - P/ES Circuit Out Of Self Test Range.
Means that 2-4 pressure switch sense circuit failure. It basically means that the transmission solenoid pack needs to be replaced.

The pressure 2/4-OD Pressure Switch is part of the pressure switch of the transmission. The pressure switch are located in the solenoid assembly. The switch provide input information to the Transmission Control Module (TCM). The switch will inform to the TCM is pressure exist in a specified hydraulic circuit. the TCM uses this information to verified that the solenoids are working or not.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shock

Possible Causes:
- Low transmission fluid level
- Dirty transmission fluid
- Faulty 2/4-OD Pressure Switch
- 2/4-OD Pressure switch poor electrical connection
- 2/4-OD Pressure switch circuit is open or shorted


Hope helps.

The low oil pressure warning lamp will illuminate when the ignition switch is turned to the ON position without the engine running. The lamp also illuminates if the engine oil pressure drops below a safe oil pressure level. To test the system, perform the following:

1. Turn the ignition switch to the ON position.
2. If the lamp does not light, check for a broken or disconnected wire around the engine and oil pressure sending unit switch.
3. If the wire at the connector checks out OK, pull the connector loose from the switch and, with a jumper wire, ground the connector to the engine.
4. With the ignition switch turned to the ON position, check the warning lamp. If the lamp still fails to light, check for a burned out lamp or disconnected socket in the instrument cluster.

REMOVAL & INSTALLATION
On the 2.4L engine, the oil pressure switch is located on the side of the engine block facing the firewall. On the 3.0L engine, the oil pressure switch is located on the oil filter adapter housing, next to the starter motor. On the 3.3L and 3.8L engines, the oil pressure switch is located next to the oil filter.

1. Locate the oil pressure sending unit on the engine.
2. Disconnect the negative battery cable.
3. Disconnect the pressure switch electrical harness.
4. Using a pressure switch socket, deep-well socket or wrench, loosen and remove the pressure switch from the engine.

To install:

1. Install the pressure switch into the engine and tighten securely.
2. Attach the electrical connector to the switch.
3. Connect the negative battery cable.
4. Start the engine, allow it to reach operating temperature and check for leaks.
5. Check for proper oil pressure switch operation.

Hope this helps (remember to rate this answerr).

install a mechanical guage to test the actual pressure, if its fine the sending unit is faulty, if nor remove the oil pan and check the oil pickup for blockage,

The oil pressure switch relays the oil pressure in the engine to the instrument cluster. The switch will illuminate the OIL PRESSURE light if the oil pressure drops below 2psi (13 pa). The switch is usually located on the side of the engine, under the intake manifold on the 2.2L engine and on the side of the intake camshaft housing on the 2.3L/2.4L engine.

Other, the low oil level switch activates the OIL light in the instrument cluster when the oil level in the pan goes below a certain level. The switch is mounted on the oil pan.
