Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Got my Durametric in the mail today and was all happy to read my engine codes. Then I saw a grocery list: P1123 (lean bank 1-3) P1125 (lean bank 4-6) P1237 (Fuel Injector, Cylinder 1 - Open Circuit) P1238 (Fuel Injector, Cylinder 2 - Open Circuit) P1239 (Fuel Injector, Cylinder 3 - Open Circuit) P1240 (Fuel Injector, Cylinder 4 - Open Circuit) P1241 (Fuel Injector, Cylinder 5 - Open Circuit) P1242 (Fuel Injector, Cylinder 6 - Open Circuit) Where do I even begin ? Hopefully the Durametric can be a yuge help Thanks

POST 2Original post

Bad grounds on the injector circuit. There is a lug on both banks. Maybe rodant damage. Just a guess.

POST 3 / ORIGINAL POSTEROriginal post

Is that problem related to the lean condition on both banks ?

POST 4Original post

You have problems with both banks being lean and all 6 injectors on both banks, so you need to look for a problem with commonality to all problems. Grounds are a good place to start, so is the MAF sensor and fuel pump. These are common things that affect all the cylinders.

POST 5Original post

Its seems logical to me but might not be correct that the injectors not firing properly or fuel starvation is causing the additional lean codes. The major cause for the lean codes by themselves is a vacuum leak.

POST 6Original post

Was engine up to temp when test was done?

POST 7Original post

The "open circuit" codes are strictly electrical in nature and specifically relate to injector wiring/power/ground/control. Inspect the injector wiring carfully and test for full 12v power / good ground ..ect. The "lean codes" are a matter of function/performance and can be injector related or related to another problem ( MAF/vacuum leak)..

POST 8Original post

Maybe they're old codes. Are you getting a CEL?
