DTC P0216: VP44 FUEL INJECTION PUMP TIMING FAILURE

Monitor & Set Conditions

Fuel injection pump operation is monitored with ignition on. DTC will set when the engine speed is greater than 300 RPM, fuel command 5 mm3/str and timing command within a certain window.

Possible Causes

• Other DTCs
• Fuel Injection Pump Gear Alignment
• Fuel Filter Restriction
• Transfer Pump Inlet Restriction
• Fuel Injection Pump

Testing

1. Turn ignition on with engine off. Using DRBIII(R) scan tool, check for engine DTCs. If DTC P0336, P1287 or P1690 is set, diagnose those DTC(s) first. See DIAGNOSTIC TROUBLE CODE DEFINITIONS. If DTC P0336, P1287 and P1690 are not set, go to next step.

2. Using scan tool, observe FREEZE FRAME data. Try to duplicate conditions recorded in FREEZE FRAME data. Using scan tool, check for DTCs. If Good Trip Counter changes to zero, go to next step. If Good Trip Counter does not change to zero, the test is complete.

3. Turn ignition off. Check for proper fuel injection pump timing and alignment of fuel injection pump drive gear. See FUEL INJECTION PUMP TIMING in ON-VEHICLE ADJUSTMENTS - RAM PICKUP - DIESEL article. If proper fuel injection pump timing and/or alignment of the fuel injection pump drive gear exists, go to next step. If fuel injection pump timing and alignment of fuel injection pump drive gear are not correct, adjust as necessary.

4. Check fuel pressure drop across fuel filter. See FUEL SYSTEMS in BASIC DIAGNOSTIC PROCEDURES - RAM PICKUP - DIESEL article. If fuel pressure drop is as specified, go to next step. If fuel pressure drop is not as specified, check for restriction and repair as necessary.

5. Check transfer pump inlet for a restriction. See FUEL SYSTEMS in BASIC DIAGNOSTIC PROCEDURES - RAM PICKUP - DIESEL article. If transfer pump inlet restriction is acceptable, replace fuel injection pump. See appropriate REMOVAL, OVERHAUL & INSTALLATION article. If transfer pump inlet restriction is not acceptable, repair transfer pump inlet line restriction
