Title : Diagnosing Hard Start / No Start, rough idle complaints or ICP pressure concerns with the CPA Tool
Applies To : EPA 2007, EPA 2010, HD OBD (2013) MaxxForce DT, 9 & 10, N9 & N10 engines
CHANGE LOG
2015/5/18 - Formatted Article
2015/4/29- Added links to SRT elemental steps
2014/12/16- Added hot test explanation
2014/11/01 - Revised formatting. Updated to CPA V5 with WAC for HPOP, ICP sensor, and 6 injectors (excessive oil leakage).
Note: 20072014 I6 High Pressure Oil Pump(HPOP) is no longer an iApprove part.
Use the diagnostics below to diagnose & repair as necessary. If HPOP replacement is needed during the warranty period it must be
accompanied by a warranty authorization code issued by the CPA tool.
DESCRIPTION
This document describes the diagnostic process for the high pressure oil system utilizing the CPA tool. The CPA tool assists in diagnosing Hard Start / No
Start / Rough idle and ICP pressure faults.
NOTE: The "Version 5" CPA software release coincides with an Essential Tool shipment 12-999-01-07 (November 2014). This CPA update allows the CPA
HPOP test to monitor engine oil temperature (EOT) and the pressure at the outlet of the high pressure oil pump.
• Version 5 requires the use of engine oil temperature (EOT) breakout tee ZTSE4602 (be sure you have this tool)
• If the CPA tool detects a failed HPOP it will issue a WAC (warranty authorization code) for the HPOP (same as version 3 and 4)
• If the CPA tool detects a failed ICP sensor it will inform the technician (new)
• If the CPA confirms that the HPOP is ok but there is excessive oil leakage under the valve cover it will issue a WAC for the replacement of 6 injectors & 6
pucks (oil inlet adaptors) (new)
• CPA V5 asks the user to identify the engine symptom. Pay careful attention to the oil temperature requirements for the different tests.
• Do not upgrade your EZ-Techs to CPA software to V5 until you have the new Essential IPR block-off adaptor for CPA (kit 12-999-01-07) available to you.
• Print the CPA HPOP V5 test set-up instructions (they are also displayed in the software) here

PROCEDURE OVERVIEW
For these tests the CPA Tool is connected to the:
• Engine oil pressure sensor (EOP)
• Engine oil temperature (EOT) new requirement with Version 5
• Injection control pressure sensor (ICP)
• IPR block-off adaptor (new version with integrated pressure sensor is required with Version 5)
• Camshaft position sensor (CMP)
The CPA Tool connects to these circuits through special breakout cables designed for use with the CPA Tool
It is strongly recommended that the CPA application be launched from ServiceMaxx.
