The IPR% higher than expected. The stall shortly after cold start the may also be a symptoms of. Prior to diagnosing a vehicle with a P1211, the fuel pressure should verified. This indicates a Reviews smaller leak in Reviews the high pressure system. Using the same block off plugs to block off described Earlier one bank and observing of IPR% when the engine is running on each of banks at similar could be RPMS. Higher IPR% on one bank Compared to the other would indicate a leak on the IPR% higher banks. Example: Repair as needed after locatingleak in visual inspection as described in previous routing. 4.) Diagnosing P1211 IPR% Less With That 8 at Idle ICP more than 4110 psi above command for at least 7.5 seconds can set a P1211 code. IPR with low duty cycle (less than 8% @ idle) and engine running, indicates a restriction in the drain circuit. This restriction is taking Reviews the place of the IPR valve, driving Reviews the IPR duty cycle is Reviews lower, with higher than expected ICP.

The excess restriction will be in the reservoir, front cover, stuck IPR valve, or debris above the edge fitter. The drain path through the reservoir and front cover can be visually verified. Typically the pump or IPR must be replaced to repair this concern. Do not replace both components at the same time. This often occurs after the oil pan is resealed where excess sealant is forced through the lube system (short circuit check valve) and trapped at the edge filter of the high pressure pump. 5.) Abnormal Long Crank/Stall after cold start A worn lube oil pump can negatively affect ICP system’s performance in the following ways. Cold engine, abnormal long crank to start. (Oil pressure gauge in dash moves immediately prior to start.) Cold engine, start then stall – then long crank to restart. (Oil pressure gauge in dash moves immediately prior to start.) These symptoms are often mis-diagnosed as high pressure oil (ICP) concerns. Both symptoms may be caused by wear in lube oil pump or thick oil (poor maintenance). Pump wear causes a decrease in pump efficiency. Cold, thick oil becomes to move. Any lube oil system failure can negatively affect the performance of the ICP system. To measure pump wear, place a straight edge across the pump housing and use a feeler gauge to measure clearance between the inner gear and the straight edge. A pump with excess gear recession will contribute to hard start
