164-E-11 Injection Actuation Pressure signal incorrect. Failure Mode is Not Identifiable.
On EMCP set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF.
Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to NORMAL.
On EMCP set ENGINE CONTROL switch to COOL DOWN/STOP. DO NOT
START THE ENGINE.
Print the lifetime totals and the configuration screen.
Check for active diagnostic codes.
a. If there are no active diagnostic codes with the ENGINE CONTROL switch in
the COOL DOWN/STOP position while the engine is off, proceed to STEP 6.
b. If diagnostic code 164-E-03 or 164-E-04 is active with the ENGINE
CONTROL switch in the COOL DOWN/STOP position while the engine is off,
repeat Troubleshooting with GSC diagnostic codes (WP 0009, SYMPTOM
If a 164-E-00, 164-E-02, or 164-E-11 diagnostic code is active with the
ENGINE CONTROL switch in the COOL DOWN/STOP position while the
engine is off, perform the Injection Actuation Pressure Test using the Cat ET
d. Continue to STEP 6 of this test if the problem is not resolved.
Try to start the engine.
a. On EMCP, set the ENGINE CONTROL switch to MANUAL START.
b. If the engine starts, proceed to STEP 9.
If the engine does not start, proceed to STEP 7.
Crank the engine and record the engine data from the Cat ET.
Record the actual injection actuation pressure.
b. Record the engine speed.
If the injection actuation pressure is above 6 MPa (870 psi), the HEUI system
is functioning correctly. Refer to Troubleshooting, Engine Cranks but Will Not
Start which is located in the Troubleshooting without a diagnostic code
d. If the injection actuation pressure is below 6 MPa (870 psi). Proceed to
