Why don't you share the Vin and all the error codes that appear after you clear them and take it for a drive. We can only help by what you're provided so far. We all assume EP6 engine but unknown version. And only looking at the code you have provided, in previous posts you mentioned other codes and now you're replaced several sensors and continue to have error codes.the P2337 sensor is bottom one ?
can the one engine error have different codes .how does that work please?thanksUpstream
