Article 94-23-15 is being republished in its entirety as part of a consolidated 7.3L diagnostic aid booklet.
ISSUE
On some vehicles there may be a loss of power at high altitudes or while pulling heavy loads at high RPMs at sea level. The MIL may also illuminate and
have codes 128 and 845 or P0236 and P0238 stored in memory. This may be due to an incorrect MAP sensor being installed during the manufacturing
process.
ACTION
Replace the incorrect black sensor with the correct grey sensor. The black sensor is incompatible with the vehicle's strategy. The grey 3 bar design is the
correct MAP sensor for the 7.3L Direct Injection Turbo Diesel.
