If the deviation between the throttle position by TPS2 signal and the throttle position by ECM/PCM's model value is bigger than the threshold value under TPS1 error, the ECM/PCM sets DTC P0221.
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
Plausibility check between TPS_1 and TPS_2 | 1. Poor connection 2. TPS 3. ECM/PCM 4. Obstruction in the throttle plate movement 5. Throttle body |
Enable Conditions |
•
Engine speed during engine start (engine operating state out of start) > 640...960rpm depending on start ECT
•
No TPS adaptation request | |
Threshold Value |
•
abs(TPS_2 - TPS_1) > 7.6% Failed TPS signal is determined by the difference between measured mass air flow and calculated mass air flow based on each TPS signal and engine speed. | |
Diagnostic Time |
•
0.3sec | |
Mil On Condition |
•
1 driving cycles. |
