Engine Error Codes P0507, P1128, P1411, P0410


Recommended Posts

I have a 2000 996 Cab4. Bought it 5 years ago. I enjoy it to no end, but it does seem to continually have issues. Last month, I replaced a/c heater control and the rear window regulator/motor.

I changed the oil last Sunday. Ended up putting 9 quarts of oil in after warming up the engine. I did not drive it much until the following Friday. The engine started idling rough. When i stop at a traffic light, the idle starts at the normal 800 rpms and then edges up to about 1400 rpms. If I blip the accelerator, the idle returns to 800 rpms.

After about 30 minutes total driving with this condition, the check engine light came on. I read the following codes- P0507, P1128, P1411, and P0410. I don't know if the oil change is related to the codes. Reading the forums it sounds like P0507 might be caused by oil separator leaking.

P1411 and P0410 have come up before. Last time, based upon forum advice, replacing the fuse for the engine compartment fan did the trick.

Anyway, my thoughts on a plan of attack is to:

1. Remove and clean the throttle body. See if that clears the codes.

2. Replace O2 sensors for bank 1. Is that the left or right side? See if that clears the codes.

3. Take it to a shop to check for vacuum leaks.

Does this make sense or are there other suggestions?

Many thanks,

Maryland

I would suggest the following approach...

1. For P0507, P1128 -- Clean the throttle body with throttle body cleaner. Also, clean the MAF with sensor cleaner. Clean and inspect all electrical connections on the the throttle body.

Clear the fault codes and see if any come back.

2. P0410, P1411 -- Check the fuse? (40A Maxi fuse near DME(behind rear seats)). Mke sure the secondary air pump is plugged in.

Clear the fault codes and see if any come back.

Loren,

Cleared the codes. After 1/2 driving, none have returned.

I believe P0410 and P1411 may be residual codes. A few months ago, when the check engine light came on, these codes appeared. At the suggestion of a forum member, I checked the engine compartment fan fuse. It needed replacing. After I replaced the fuse the check engine light went off. I never went in and cleared the codes. So my thought is that the codes have been sitting in the engine module since the prior incident and had nothing to do with the rough idling.

Does this make sense?

Thank you for all your help and best regards,

Maryland
