Engine Intake Valve Actuation System Oil Pressure : Not Responding Properly E1101 (2)
Intake Valve Actuation System Oil Pressure #1 Not Responding to Command The Engine Intake Valve Actuation System Oil Pressure did not change when the Engine Intake Valve Actuation System Oil Pressure solenoid is toggled.
2948-17
Engine Intake Valve Actuation System Oil Pressure : Low - least severe (1) E488 (1)
Low Intake Valve Actuation Pressure The Engine Intake Valve Actuation System Oil Pressure solenoid is commanded closed, but the oil pressure does not go up.
2949-7
Engine Intake Valve Actuation System Oil Pressure Control Valve : Not Responding Properly 1922-7
Intake Valve Actuation System Oil Pressure Solenoid : Not Responding Properly This code indicates that the difference in rail pressure is incorrect while the control valve is opened and closed. The following conditions can cause this code:
A control valve that contains debris or a control valve that is not operating correctly
Damaged O-ring seal or missing O-ring seal.
2950-7
Engine Intake Valve Actuator #1 : Not Responding Properly 1901-7
Intake Valve Actuator #1 : Not Responding Properly The intake valve actuator is not responding correctly to the commands from the ECM. This error can be caused by the following conditions :
There is an oil leak in the system.
There is a problem with an actuator.
The valve lash is incorrect.
The adjustment of an actuator is incorrect.

Troubleshooting Test Steps Values Results
1. Check the Engine Oil Level
A. Stop the engine. Allow the engine to cool approximately 20 minutes so the oil level can stabilize.
B. Check the engine oil level.
Oil level
Result: The engine oil level is OK.
Repair: Record the engine oil level. Verify that the dipstick is calibrated correctly. Refer to Operation and Maintenance Manual, "Engine Oil Level Gauge - Calibrate".
Proceed to Test Step 2.
Result: The engine oil level is low.
Repair: Verify that the dipstick is calibrated correctly. Add engine oil to the proper level. Record the amount of engine oil that was added.
If the problem has not been eliminated, proceed to Test Step 2.
Result: The engine oil level is high.
Repair: Verify that the dipstick is calibrated correctly. Record the amount of engine oil that was drained.
If the problem has not been eliminated, proceed to Test Step 8.

Troubleshooting Test Steps Values Results
2. Check the Engine Oil Pressure
A. Turn the keyswitch to OFF.
B. Establish communication between the Cat® Electronic Technician (ET) and the ECM. Refer to Troubleshooting, "Electronic Service Tools" for more information, if necessary.
C. Install a mechanical gauge to the engine to read the engine oil pressure. Refer to Testing and Adjusting, "Engine Oil Pressure - Test".
D. Turn the keyswitch to OFF.
Engine oil pressure Refer to Table 3
Result: The engine oil pressure is within specifications.
Proceed to Test Step 3.
Result: The engine oil pressure is low. Record the engine oil pressure. Record the engine rpm.
Repair: If there are any codes related to low oil pressure, refer to Troubleshooting, "Oil Pressure Is Low".
Result: If the pressure is constant throughout the rpm range, there is a problem with the circuit for the engine oil pressure sensor.
Repair: Check the wire for the pressure sensor supply terminal A for an open circuit.
Result: If there are no codes related to low oil pressure, refer to Testing and Adjusting, "Engine Oil Pressure - Test".
3. Check for Codes
A. Connect to Cat ET.
B. Turn the keyswitch to ON.
C. Check for active or logged codes.
Codes
Result: A 1922-7 or 2949-7 code is active or logged.
Proceed to Test Step 4.
Result: A E488 (2), E1101 (2), 2498-7, or 2948-17 code is active or logged.
Proceed to Test Step 5.
Result: A 2950-7 through 2955-7 or a 1901-7 through 1906-7 code is active or logged.
Proceed to Test Step 8.
