Can someone tell me what CEL code P0418 is? Used a generic ODB2 reader.

Thanks

This is what I found online:

P0418 Description
An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump. The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.

More then likely a evap canister purge valve leak Karma doesn't use a air pump and I'm only guessing by your description I don't use a Generic code reader

Have Joe send you his remote fisker magic code reader/hypnotic programmer.....


Or Go to suburban tomorrow and pay them to read your codes and email you the screen shots and then forward them to Joe.

Then tell them to do whatever Joe says the car needs - I did that once. DH

FYI - The 5 digit code I see in my Generic code reader (PIB48) was called PIB4800 by my CSP. Don't know if that's how it always works with these generic codes, but I thought I'd mention it.

With the amount of generic codes and factory codes it's very hard to convert them over . Most engine related codes for emission faults are the same . I'm working on a problem car now a P0014 generic code is the same as the code I get with Prodis . The Prodis has one more zero .
When it comes to the Hybrid side nothing will match .
