Broken Oil pressure sensor? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Dream20b · 12-24-2015, 01:06 AM

Okay, So tonight I was driving and about 5 minutes into my drive I heard this banging noise, it was very loud and increased and decreased with RPMs. I've managed to get home with the car but not until after calling a tow truck.

Long story short, Car chugged and then died, refuses to start at all. I did some searching in the engine bay and found the wiring part in the Attached image to be broken. Does anyone know what that piece is called? I think its the Oil Pressure Sensor. If this is really broken, could this cause a no-start condition? Car still doesn't start, no clicks, no nothing. Lights on dash come on and the battery is good.

Yah, that looks like it could be the oil pressure sensor, but the pounding / banging noise sounds like it's something else. Any warning lights come up on the dash (CEL / oil)? Did the loud sound seem like it was something from within the engine / internal (although, chances are it definitely was, seeing as your car refuses to start).

Maybe someone who's had a similar issue can chime in. I've had issues with oil pressure sensors on one of my older cars in the past, but they never cut the engine out, so I would doubt that is the issue here.

Yeah, that's the oil pressure switch. If it was disconnected you would have no warning light for loss of oil pressure. Bang and knock sounds like a thrown rod or spun bearing. Likely due to oil starvation.

How much oil on the dipstick?

Op dude you might want to include mods, it appears you running a sprintex SC kit on E85 judging by your other posts

that oil pressure sender looks ok,is wire still connected.

knocking\banging sounds pretty terminal.

Ultramaroon · 12-24-2015, 03:44 AM

Ok, as Steve said, "More info."

Yep looks like you have some form of electrical problem as well

could be a simple as a dead battery

C1201 ABS rear valve failed
C1234 ABS module error
U0100 General communications fault between ECM and PCM power train control module

seem a bit unrelated unless battery has failed or SC belt has let go and damaged wiring or similar.

As for the knocking/banging that does not sound good, it possible it may be due to control module issues but sound more of a mechanical problem.

Hmmm... I would need eyes and hands on to get any further.

Dream20b · 12-24-2015, 04:44 PM

I'll be wrenching tonight

BRZnut · 12-24-2015, 05:59 PM

keep us updated. Good luck

Dream20b · 12-24-2015, 07:41 PM

Smells faintly like e85 when I pull the dipstick. No leaks under the car after sitting 12 hours. Oil level is normal, maybe a tad high.

Dream20b · 12-25-2015, 12:30 PM

Found some pieces of belt near the rear of the engine bay. However, as far as I can tell, the belt is till in tact and I can trace it all the way around the top half of the motor. this piece of belt may be from a previous shredded belt.

Ultramaroon · 12-25-2015, 03:15 PM

Did you reconnect that lead to the oil pressure switch before you took the photo, or did you take that snapshot as-is?
