Duramax p1093
Fluorescent to led conversion kit
DTC Codes (Check Engine Light) DTC P1093, P0087 causing limp mode is common with this issue. Low rail pressure may or may not cause an MIL (check engine light). This is a very common problem that we hear about from our Duramax customers. Actual fuel rail pressure is not keeping up with desired fuel....
It eliminates potential low fuel rail pressure DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment) that are caused by insufficient pressure relief valve spring pressure opening, returning fuel to the fuel tank. Requires the use of a Viton O-Ring sold separately. (113073001)
