I recently replaced the thermostat on my 2014 Nissan 370Z. After completion of the repair, the car started throwing a P117A code. The car seems to run fine, with no noticeable change in performance. I can clear the code, but after a few miles, it will throw it again. It was not throwing this code prior to replacing the thermostat. Any ideas?
-
Unfortunately I can't find any information about the P117A. I have checked all my factory manuals and there is no code for the P117A code on the 2014 Z.
-
I replaced the spark plugs and ignition coils on my 2013 Nissan altima and now it's running bad and throwing code p117a. What can I do to try and fix it without taking it to a shop?
-
If you didn't have that problem and code before, then my only suggestion is to double-check the installation. Make sure you didn't cross the coils' connectors, and that all the ignition coils are fully connected."
