Help with codes P1130 and P0117

[natzee]

Hi guys,

It is now my turn to get the CEL :D . I plugged in the scanner and got these codes P1130 and P0117.

I have been reading the forum and noticed the P1130 can be the MAF and the P0117 has to do with the coolant temp sensor.

If anybody has any input based on the experience, I would appreciate it.

Thanks in advance,

-Nat

P0117 Engine Temperature Sensor - Below Lower Limit

A fault is recorded after a debounce time of 0.4 seconds if an engine temperature of less than -42 °C is measured.

Fault conditions - Short circuit to ground.

Fault area - Wiring, Temperature sensor, DME control module.

P1130 Oxygen Sensing Adaptation Area 2 (Cylinders 4 - 6) - Rich Threshold

Fault conditions - Fuel/air mixture is so lean that sensing has reached its rich threshold.

Fault area - Intake air system leaking, Fuel pressure too low, Volume supply of fuel pump too low, Fuel injectors fouled.

Since you only got a P1130 I don't see how it could be the MAF. Fault P1130 is only affecting one side of the engine and the MAF should affect both.

I would fix the temperature sensor then reset the codes. IF the P1130 comes back then start looking for an intake air leak.

Thanks Loren :D

Hi Loren,

I fixed the temperature sensor and clear the code. Now the CEL comes back and I am getting these new codes:

P1315 Misfire, Cylinder 3, Emission Relevant

P1316 Misfire, Cylinder 4, Emission Relevant

P1317 Misfire, Cylinder 5, Emission Relevant

P1318 Misfire, Cylinder 6, Emission Relevant

P1319 Misfire, Emission Relevant

Do you know, what can be the culprit for these codes? I did check my gas/oil caps.

Thx,

Have you changed the spark plugs recently?

Fault area

- Fouled, faulty or incorrect spark plugs

- Contact resistance (coils)

- Loose contacts

I replaced the spark plugs when the car was @ 65K miles now it is 81K miles. I used the platinum plus 4 plugs. Don't know if these plugs are the cultprits since there was a discussion about it.

Another local guy that did not go to the OBD II tech session 2 days ago. :P

I think I have amnesia.

Nat,

Do you have the part number for the plugs? So we can figure out if they are the wrong heat range or profile.

I went to the site (don't want to tell the name here :-) ) and looked for the part #, guess what.... they don't carry it any more.

Look through my record and found it, here is the info:

Parts Ordered

Porsche 1997 Bosch Spark Plug Platinum+4

Qty: 6

Part #: F1000-61923

Interestingly enough, I also ordered 18 plugs (+4) for my mercedes at the same time. Now my mercedes is also acting a bit strange lately. I will order the new sets of plugs and replace them this weekend. I will let you know if this is the problem.

Thx,

-Nat

P.S Jeff, I was planning to attend the tech session but things came up and I got stuck :-)

Porsche does not use the Platinum+4, just your normal copper plugs.

No clue if it is related to aftermarket plugs. More so since they have been in for 16,000 miles.

Ok the saga continues :-),

I purchased new fuel filter and new set of spark plug (NGK with copper 2 electrododes) to give this a try.

Put in new plugs and new air filter and fuel filter plus getting a nasty cut on my finger :-(.

Since, I already had the car at the service position, I gave it a new oil/oil filter change.

Now, I clear out the codes and start turn on the key. Guess what, the CEL is blinking and then stay on.

Plug in the code reader and there you go: P0300, P0306, P0304 ....P0305 plus the old code P1316-P1319.

Anybody, has any idea? look like I may need to contact Tim at Porsche Fast Lane for a 3.4 up grade :-).

Ok, I will call it a day (work on car for me).

If anybody has any suggestion, I will appreciate it.

The problems solved:

First I want to say "THANKS" :clapping: to Loren for helping me to track down what the codes were, they were very helpful.

Here are what I found:

- A leak in the air intake.

- Connection to the plugs were not plug-in correctly.

- Need new fuel filter

- The platinum plus 4 are not good for the boxster.

It always, good to put a bottle of techron into the gas tank to clean out the injectors and valves.

:drive:
