SOURCE: Audi 80 oil pressure light

your oil pressure switch is faulty,or the loom going to it is grounding off the engine block, The switch is beside the sump,disconnect the switch and check if the lamp has went out,if it has replace the switch,if it hasn't replace/repair the wiring.
The switch shorts and the output from switch to dash is then grounded through the bolts that holds the switch in place.

SOURCE: where is the oil pressure sending unit located?

The pressure sending unit is located on the passenger side rear of the engine just above and slightly to the left of the filter and filter housing.

SOURCE: where is the oil pressure switch on a 2001 f150

Left ( driver's side ) front of the engine on the 5.4L engine.

This is shown to be at the end of the baffled area of the intake, the edge of the pleated area farthest from the airfilter ( looking at the engine, the left side of the pleated folds ).
When you locate this, look down the front of the engine.

The connector is a black 1 pin connector with a White w/ Red Stripe wire to it.

You might have to remove the factory air intake plastic housing to see it.

Have a 2001 pontiac aztec i change fuel pump but still giving problems put in the computer give me p0102 and p1189 replaced them still the same whats next


P0102 - The mass air flow (MAF) sensor is an air flow meter that measures the amount of air entering the engine. The powertrain control module (PCM) uses the MAF sensor signal in order to provide the correct fuel delivery for a wide range of engine speeds and loads. A small quantity of air entering the engine indicates deceleration or idle. A large quantity of air entering the engine indicates an acceleration or high load situation. The MAF sensor has an ignition 1 voltage circuit, a ground circuit, and a signal circuit. The PCM applies a voltage to the sensor on the signal circuit. The sensor uses the voltage in order to produce a frequency based on inlet air flow through the sensor bore. The frequency will vary within a range of around 2,000 Hertz at idle to about 10,000 Hertz at maximum engine load. DTC P0102 will set if the PCM detects a frequency signal lower than the possible range of a normally operating MAF sensor.
Sounds like you need a mass air flow sensor , but take it to a ASE certified repair shop an have it check , instead of just replacing it.
DTC P1189
The engine oil pressure switch is a normally closed switch that opens with the proper oil pressure. With the ignition switch turned ON and the engine not running, the PCM should detect a low signal voltage input. With the engine running, the pressure switch opens, and the PCM should detect a high signal voltage input. The PCM tests the state of the engine oil pressure circuit with the ignition switch turned ON, and the engine turned OFF. If the PCM detects a high voltage input on the engine oil pressure signal circuit, DTC P1189 will set.

ENGINE CODE P1189 2002 MONTE CARLO


Diagnostic Test Code (DTC) P1189

Description: "Oil Pressure Switch Signal Voltage Is High"

The engine oil pressure switch closes when there is low oil pressure, making the sensor signal voltage low. The switch opens when the oil pressure is above 4.5 Psi, making the sensor circuit voltage high. The Powertrain Control Module (PCM) monitors the oil pressure switch and sends a class 2 message to the Instrument Panel Cluster (IPC) to tell it if the switch is open or closed. DTC1189 is set when the PCM determines that the sensor signal circuit is high with the ignition switch in the RUN position for more than 10 seconds.

Both the PCM and IPC must be scanned and the data must be checked and verified before the actual cause of this code can be accurately determined. This can be caused by a number of different things including: low engine oil pressure, a malfunctioning oil pressure switch, broken wires or bad connectors, or a defective IPC or ECM.

P1189


P1189 = Engine Oil Pressure (EOP) Switch Circuit

With the GA, the OP 'low pressure' (below about 8 psi) disables the Fuel PUMP

Also check Fuse #37 (AC compressor) which has some wierd subcircuits that can cause this condition.

We are trying to find out if my 1997 buick le sabre has an oil pan sensor or oil pressure sensor and where it is located at so that we can change out the oil pan


all car well have a oil pressure sensor, the oil pressure sensor is what lets you know, you have good oil pressure, if light comes on low oil pressure, need to turn off engine before major engine damage occurs, the oil pressure switch will be next to the oil filter, screw into the engine block, your car also has a oil pan sensor, called oil level sensor, that one screw into the side of the oil pan, it let you know when your some what low on oil.

I have a code p1189 come up on a computer when the


P1189 Engine Oil Pressure Switch Circuit

The problem is the car does not have the Catalytic converter. You should have a check engine light for the lack of Catalytic converter since there should be a O2 sensor back there monitoring the exhaust system. The leak of Catalytic converter will also drop your back pressure which the new engines need to run 100%. Without the proper back pressure, it throws off the MAP sensor readings and is causing a conflict in your engine's management parameters. You can get an aftermarket Cat for under $80.00. Good luck and keep me posted.
