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.

Just got there codes for my 2000 323I P1250 P1188 P1189 P0304 P0173 P0170 It pass the test,anyone have any ideas ???


P0304 = #4 cylinder misfires
P0170 = Fuel Trim, Bank-1
P0173 = Fuel Trim, Bank-2
P1250 = this is invalid code for BMW
P1188 = Fuel control, bank-1, sensor-1 (pre-cat sensor)
P1189 = Fuel control, bank-2, sensor-1 (pre-cat sensor)
Vacuum leaks and/or sensor defective for the issues of the codes.
This error codes really need parts to replace. But you have to replace the thermostat first. Then clear the codes and see if any reappears,then replace defective part/s

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.

Just got there codes for my 2000 323 and it didebt pass e test...p1250 p0173 p0170 p1189 p1188 dose anyone have any idea???


p1188: Fuel Control (Bank 1 Sensor 1)
p1189: Fuel Control (Bank 2 Sensor 1)
p0171 and p0173: These are very common codes on BMW's which can also be false codes, try clearing the codes and run the test again they may not come up again.
p1250: Never came across that....

Need to know what p1188 is to diy er


SAE Code P1188 DTC Code 17596 Description Linear 02 Sensor / Compensator Resistor Short to ground SAE Code P1189 DTC Code 17597 Description Linear 02 Sensor / Compensator Resistor Short to B+ SAE Code P0170 DTC Code 16554 Description Fuel Trim, Bank1 Malfunction

Basically you need a new oxygen sensor, The fuel trim code is from the computer trying to adjust the fuel/Air mixture to compensate for the bad signal from the sensor. Just change the one closer to the engine, the one behind the Catalytic converter will thow a different code when it fails.
