This is your Oil Pressure sensor. You can have it tightened or replaced and this will solved the problem. Depending on where it is leaking from on the sensor will determine the action to take. Threads area leaking, I would tighten the sensor first. Leaking around the plugin, I would replace the sensor and as soon as possible.

SOURCE: I have an oil leak, oil shows up on top of the engine.

Spray cold engine down with carb cleaner or brake cleaner. Let air out. Keep watch on where you first see the oil. It is most likely from your valve cover gasket.

Sounds like valve cover gasket is leaking. It leaks down side of engine onto everything in it's path. Stop by a local parts store and have them take a peak, they'll be glad to help you out.

Hi, your bank 1 upstream oxygen sensor is malfunctioning. Recommend you replace the sensor. It is likely this will clear both trouble codes. The sensor is mounted in the rear exhaust manifold, near the firewall. Please let me know if you have questions, and thanks for using FixYa.

Trouble Code: P0430

Catalyst System Efficiency Bank 2 Below Threshold
Possible Causes:


Air leaks at the exhaust manifold or in the exhaust pipes Catalytic converter is damaged, contaminated or it has failed ECT/CHT sensor has lost its calibration (the signal is incorrect) Engine cylinders misfiring, or the ignition timing is over retarded Engine oil is contaminated Front HO2S or rear HO2S is contaminated with fuel or moisture Front HO2S and/or the rear HO2S is loose in the mounting hole Front HO2S much older than the rear HO2S (HO2S-11 is lazy) Fuel system pressure is too high (check the pressure regulator) Rear HO2S wires improperly connected or the HO2S has failed

Trouble Code: P2197

Lack of HO2S-21 Switching, Sensor Indicates Lean
Possible Causes:


Base engine problems: engine oil level high, camshaft timing error, cylinder compression low, exhaust leaks in front of HO2S EGR System problem: EGR valve is stuck open, the gasket is leaking, or the EVR diaphragm is leaking Fuel System problem: damaged fuel pressure regulator or extremely low fuel pressure HO2S problems: HO2S circuit is open or shorted in the wiring harness or the HO2S is damaged or it has failed Induction System problems: air leaks after the MAF sensor, PCV system leaks, engine vacuum leaks or dip stick not seated

Trying to track down oil leak need cutaway to help find possible locations on engine that could leak motor oil


Best is to pressure wash it - then run and inspect it after the run.

If it's at gearbox join - suspect main crank seal
If it's near oil filter - replace gaskets there.
If near cambelt - expect to replace seals behind there.
Or head gasket.

The oil is leaking from wherever you see oil on the engine. Sometimes there can be to much oil covering the engine and it needs to be degreased. A dye can also be added to the oil that will illuminate when a dye light is used to help track down a leak. If the oil pressure switch you removed wasn't wet with oil or leaking than it wasn't bad.

It could be anything from the valve cover gaskets, cam seals, front crank seal, oil pan gasket, rear main seal or head gaskets.

OK, does it appear that the oil pressure sensor is leaking through the plastic to metal seam (on the sensor itself)?

Have had an oil pressure sending unit go bad and leak on a 1990 Oldsmobile Cutlass Calais that needed to be replaced.

REMOVAL & INSTALLATION C1500 Suburban 1994
  1. Disconnect the negative battery cable and drain the engine oil.
  2. Disconnect the sensor electrical lead and unscrew the sensor. The sensor can be found on the top side of the engine, near the distributor. To install:
  3. Coat the first two or three threads with sealer. Install the sensor and tighten until snug. Engage the electrical lead.
  4. Connect the battery cable and fill the engine with oil.

What is the part call that the oil filer screws on called. it seems to be leaking from there


Check that the oil filter if firmly screwed onto the engine. If not then drain the oil, undo the oil filter. Wipe the surface of the oil filter connector on the engine so its clean. Get a new oil filter and smear a small amount of oil on the rubber seal. Screw the filter into place making sure it is a tight seal. Re-fill the engine with the right amount of oil. You should be good to go. Check that the oil leak is coming from the filter before you start as it could be something more serious eleswhere like the head.

Oli leaking 1990 yj


Look for leaks high on the engine, like valve cover gaskets...

High oil pressure, if you actually had that, would not necessarily exit the engine....Crankcase pressures are not related to system pressure, per se.

Get a mirror and inspect very carefully.. Sometimes you have to clean the engine and test again, as air blows leaks all over (while driving...)

LOCATING CRANK SHAFT POISITION SENSOR ON 2002 NISSAN 2.5


The crankshaft position sensor is located on the back side of the engine, in the engine block near the oil pan towards the transmission. If you take the engine cover off of the top of the engine and look down the back of the block past the intake you can see the sensor and the harness going to it.

2003 ford taurus what to do to fix,have codes 1131 and 1151.


error codes 1131 and 1151 say : Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean - Bank No. 1 (1131) and 2 (1151).

a lot of causes are possible:

* Short to VPWR in the harness or HO2S
* Water in the harness connector
* Open/shorted HO2S circuit
* Corrosion or poor mating terminals and wiring
* Damaged HO2S
* Damaged PCM
* Excessive fuel pressure
* Leaking/contaminated fuel injectors
* Leaking fuel pressure regulator
* Low fuel pressure or running out of fuel
* Vapor recovery system
* Air leaks after the MAF
* Vacuum Leaks
* Improperly seated engine oil dipstick
* Leaking gasket
* Stuck EGR valve
* Leaking diaphragm or EVR
* Oil overfill
* Cam Timing
* Cylinder compression
* Exhaust leaks before or near the HO2S(s)

the idle up and down is because the electronics ist stuck in a try to compensate, overcompensate, reset cycle
