Ck engine light
 
Came on at 7000 miles on my 2013 Wrangler. Reset myself twice because I thought it was the gas cap, it started first start after fillup. Had to go the dealers they said it is my oil pressure sending unit. I asked if they were absolutely sure, they said yes. Had to order the part. Plenum needs to be pulled for that. I really don't like the idea of them pulling it apart. Any comments/suggestions will be appreciated.

What was the code it set?

moemoe88 11-24-2013 08:09 PM

Let's see on my receipt it says cause 100 engine 141
Does that sound like it or I don't know and didn't ask.

ronjenx 11-24-2013 08:20 PM

It would be a P code, such as P06DD

moemoe88 11-24-2013 10:52 PM

It's not anywhere on the receipt.

Why are you worried about them fixing it? You will pay for someone else to do it.

p0520 from AutoZone

Not real worried about them fixing it, more worried that it is the problem and not something else

COLOUXJ 11-25-2013 03:22 PM

Do you mean P0522? Im not seeing a P0520

psychoteen101 11-25-2013 03:40 PM

2013 wrangler with less than 10,000 miles is under warranty. No sense in paying someone to diagnose it, dealer will fix it for free. Bring it back to them until its fixed.

COLOUXJ 11-25-2013 03:42 PM

And if it is P0522 Then thats low oil pressure, which probably mean that the sending unit is bad or you're running low on oil.

moemoe88 11-25-2013 04:05 PM

Yes AutoZone is general and has about 6 or 7 possibilities for the cause including the sensor, oil pressure, etc.
Of coarse I am having the dealer fix it under warranty, just bugs me that they have to take so much of it apart with it being so simple.

P0520-ENGINE OIL PRESSURE SENSOR CIRCUIT


When Monitored: Ignition on, engine not running.

Set Condition: The Powertrain Control Module (PCM) senses the oil pressure is out of the calibrated range. One Trip fault.

NOTE: Make sure that the engine oil is at the proper level. Also, review the customers oil change history to ensure that the oil is being changed at the correct intervals and that the proper oil viscosity is being used.


Possible Causes

ENGINE OIL PRESSURE SENSOR SIGNAL CIRCUIT SHORTED TO VOLTAGE

EXCESSIVE RESISTANCE IN THE (G6) ENGINE OIL PRESSURE SIGNAL CIRCUIT

ENGINE OIL PRESSURE SIGNAL CIRCUIT SHORTED TO GROUND

EXCESSIVE RESISTANCE IN THE (F855) 5-VOLT SUPPLY CIRCUIT

5-VOLT SUPPLY SHORTED TO GROUND

EXCESSIVE RESISTANCE IN THE (K900) SENSOR GROUND CIRCUIT

ENGINE OIL PRESSURE SENSOR

POWERTRAIN CONTROL MODULE (PCM)

I changed the oil at 6000 miles, put 5-30 in it. I guess it called for 5-20. Wonder if that is an issue. I have been checking the web and there seem to be some issues with this function, including the oil pump. That's the kind of stuff that worry's me.:eek:

People run 0w-40 without problems.

Bring it back to the dealer. If its still under warranty and you or another shop messes with it, they can void the warranty. Make sure they verify with a mechanical gauge the oil pressure is within specification.
