P1238 ODB-II Code

Post by FLipRaY »

I'm trying to get some ideas on this code on my 2002 v70xc. Car would start, idle, then bog down and die after a few seconds. Feels like a really bad misfire. Pulled a P1238 "Cyl 2-Fuel Inj Circ Open Circ" according to my OBDII reader. But when I look up the code around here, it's pointing to a bad TC Control Valve according to a post but also saying it's a "Fuel Pump Secondary Circuit Malfunction" based on this list: https://www.matthewsvolvosite.com/forums ... =4&t=20628

Any ideas on which route chase? #2 injector, TC valve or actual fuel pump issue? Any help is appreciated.

I believe your 2001 uses the same engine management as my 1999 - and the P1238 maps over to ECM 6806

ECM-6806 TURBOCHARGER (TC) CONTROL VALVE
FLOW TOO LOW - PERMANENT/INTERMITTENT FAULT

That usually means bad hoses, clamps, splits, hole in hose, looseness in induction.
