The procedures given in this section for valve lash adjustment are to be performed at the initial 38,000 km [24,000 mi] adjustment. Subsequent adjustments are to be performed at 77,000 km [48,000 mi] intervals. With a 15 mm wrench, remove the valve cover. 1/2 Inch Drive, 3824591 Engine Barring Gear Locate Top Dead Center (TDC)…
A hard start or no start issue can be a troublesome problem to run into on the 7.3 Powerstroke. There are a number of sensors and other engine components that can cause both of these issues which makes it difficult to pinpoint what the exact problem might be. This guide is going to discuss the…
Power Stroke OBD-II Code P1211 – “ICP Higher/Lower Than Desired” (7.3L) OBD-II Code P1211 from a 7.3 Liter Power Stroke is often caused by running “Hot Chips” or tunes that are demanding more ICP (Injection Control Pressure) than the HPOP (High Pressure Oil Pump) can deliver and can be accompanied by a lack of power or…
The 7.3 Power Stroke diesel engine is: a four-cycle turbocharged V-8 with overhead valves. 7.3 liter (444 cubic inch) displacement. Separated into two banks, the right bank numbered 1, 3, 5, 7 and the left bank numbered 2, 4, 6, 8. rated at 250 horsepower for automatic transmission and 275 horsepower for manual transmission. The…
Purpose:To determine if the PowertrainControl Module (PCM) has detected any fault conditions that would cause a hard start or no start condition. Key On Engine Off (KOEO) On-Demand Self Test is a functional test of the PCM performed on demand with the key on and the engine off. This test will check that all inputs…
Purpose:To determine if the injection control system can supply enough injection control pressure to sustain starting. Recommended Procedure:Connect OBDII Scan Tool to the data link connector (DLC) under the dash. Access ICP PID on Scan tool menu nd monitor ICP reading while cranking the engine. Note: CMP signal is required before injection control pressure is allowed…
Key On Engine Off (KOEO) Injector Electrical Self Test is a functional test of the PCM performed on demand with the key on and the engine off. This test determines if the injector circuits and solenoids are electrically operating without fault. All injectors will first buzz (audible feedback of the injector solenoids energizing the injector…
7.3 Powerstroke IPR General Info: A Power Stroke engine utilizes an electromagnetic spool valve, to regulate the HP oil pressure on the engine to tailor the injection characteristics of the injectors. This valve is called the Injection Pressure Regulator or IPR. In the 7.3 Power Stroke engine, pressure control in the injector control pressure system…
Controlled venting is provided at the injection pump through the fuel drain manifold. Small amounts of air introduced by changing the filters or injection pump supply line will be vented automatically, if the fuel filter is changed in accordance with the instructions. No manual bleeding of fuel lines is required. NOTE: Manual bleeding is required if:…
Cause Correction Low Fuel Level in Tank Fill fuel supply tank. OK Idle Speed Too Low Check / adjust low idle screw setting. OK Air in the Fuel System Bleed fuel system and check for suction leaks. OK Fuel Supply Restricted Clean or replace pre-filters and screens, check for fuel line restrictions. OK One or more…
Cause Correction Idle Speed Too Low Adjust Idle Speed. OK Engine Driven Units Engaged Disengage driven Units and check for loading from malfunctioning accessories. OK Malfunctioning Engine Shutdown Device Make sure shutdown is not occurring too soon. OK Air in the Fuel System Bleed the fuel system and check for suction leaks. OK…
Cause Correction Incorrect Starting Procedure Refer to “The Starting Procedure Matrix“. OK No Fuel in Tank Add fuel. OK Electric or Manual Fuel Shutdown Not Open Check for loose wires and verify that the solenoid is functioning. Check to be sure the manual shut-off lever is in the “Run” position. OK If the condition occurs…
