Codes for Intermittent Errors
P2- Blend door could not reach desired position. Possible failure had occurred at evaporator assembly or wiring to blend door actuator.
P3- ln-vehicle sensor was open.
P4- Ambient sensor (mounted on radiator support) was open.
P5- Sunload sensor (mounted on defroster grille) was short.
P6- Blend door travel was out of range. Possible failure had occurred at evaporator assembly or wiring to blend door actuator.
P7- Blend door could not calibrate. Possible failure had occurred at evaporator assembly or wiring to blend actuator.
P8- In-vehicle sensor was short.
P9- Ambient sensor (mounted on radiator support) was short.
P codes indicate intermittent errors. That is, since the last battery hookup, a failure had occurred but has corrected itself. To clear P codes, depress the COOL button for three seconds. Check circuit to make sure the condition has been resolved.
NOTE: P codes are automatically erased after 100 'ignition on" cycles.
