Conditions for Clearing the DTC



DTCs P0638, P2100, P2101, P2102, P2103, and P2119 are Type A DTCs.



Diagnostic Aids



Inspect for a condition in which the throttle valve may have been held open. For example, ice may have formed in the throttle bore causing the



throttle valve not to close.

Circuit/System Verification



1. Ignition ON, observe the DTC information with a scan tool. Verify DTC P0121, P0122, P0123, P0221, P0222, or P0223 is not set.



瀚慖f a DTC is set refer to DTC P0121-P0123 or P0221-P0223 (Without LF1, LFW) ( See: P Code Charts/P0121) for further diagnosis.



2. Observe the scan tool Throttle Position Sensor voltage parameters. Verify that Throttle Position Sensor 1 voltage is between 3.24-3.54 V, and



Throttle Position Sensor 2 voltage is between 1.36-1.86 V.



瀚慖f either Throttle Position Sensor voltage is not within the specified range refer to DTC P0121-P0123 or P0221-P0223 (Without LF1,



LFW) (See: P Code Charts/P0121) for further diagnosis.



3. Rapidly depress the accelerator pedal from the rest position to the wide open throttle position (WOT) and release the pedal. Repeat the



procedure several times. DTCs P0638, P2100, P2101, P2102, P2103, or P2119 should not set.



瀚慖f a DTC P0121, P0122, P0123, P0221, P0222, or P0223 set while performing this procedure refer to DTC P0121-P0123 or



P0221-P0223 (Without LF1, LFW) (See: P Code Charts/P0121) for further diagnosis.



4. Slowly depress the accelerator pedal to WOT and then slowly return the pedal to closed throttle. Repeat the procedure several times. DTC



P0638, P2100, P2101, P2102, P2103, or P2119 should not set.
