- Engine:
- C15 (S/N: BXS1-UP; MXS1-UP)
Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.
Problem
When the diagnostic codes are active or logged in Table1 below the 224-4535 Pressure Sensor Gp and 248-2168 Pressure Sensor Gp are being replaced mistakenly.
Solution
When the diagnostic codes that are associated with the intake valve actuation pressure sensor are logged or if the codes are active, Do Not replace the 224-4535 Pressure Sensor Gp or the 248-2168 Pressure Sensor Gp . Refer to Table 1 for the diagnostic codes that do not require replacement of the intake valve actuation pressure sensors.
Use the list of troubleshooting procedures below to help determine the nature of the mechanical failure. The list of troubleshooting procedures below can be found in the engine troubleshooting guide Troubleshooting, SENR9698, "C11,C13,and C15 On-Highway engines".
- Intake Valve Actuation System Oil Pressure Circuit - Test
- Intake Valve Actuator Circuit - Test
