The codes while not running were: 172 O2 sensor Bank1 lean;
211 PIP Circuit failr (?); & 556 fuel pump relay circuit failure.
I swapped the horn relay with the pump relay, with no diff results.
The 172 should be lean since its not running. right? and 211 could mean misfire and it is not running so now what?
They said the codes get erased when the engine is turned off. Is that correct? I why couldn't they get a code when it was running. They couldn't.
