P117A - Engine Oil Over Temperature — Forced Limited Power
Description: This DTC sets when the engine oil protection strategy is enabled when the engine oil temperature reaches a
predetermined level in the PCM. The PCM then limits the engine RPMs until the engine oil temperature returns to normal.
Possible Causes: • Engine overheating
• Low engine coolant
• Loaded weight is greater than the maximum vehicle weight rating. Refer to the Owner's Literature for
vehicle weight ratings.
Diagnostic Aids: This DTC is an informational DTC and may be set by an engine overheating concern. If the engine overheats,
check the cooling system. Refer to the Workshop Manual Section 303-03, Engine Cooling, to diagnose the engine overheats symptom.

P1260 - Theft Detected, Vehicle Immobilized
Description: This DTC can be set if the passive anti-theft system (PATS) has determined a theft condition existed and the
engine is disabled or an engine start was attempted using a non-PATS key. This DTC is a good indicator to check the PATS for DTCs. This DTC can also be set when a new instrument panel cluster (IPC) or PCM is installed without correctly programming either module even if the vehicle is not equipped with PATS.
Possible Causes: • Incorrectly programmed PCM
• Incorrectly programmed IPC
• Previous theft condition
• Anti-theft system concern
Diagnostic Aids: Theft indicator flashing rapidly or on solid when the ignition is in the ON position. Check the anti-theft system for
DTCs. Refer to the Workshop Manual Section 419-01 Anti-Theft, Diagnostic Trouble Code (DTC) Charts to continue diagnosis. If a new IPC or PCM is installed without correctly programming either module, the parameters must be reset in both modules. Refer to the Workshop Manual Section 419-01 Anti-Theft, Passive Anti-Theft System (PATS) Parameter Reset, to continue diagnosis.
