PCM sets DTC P0222 if the PCM detects signal voltage lower than the possible range of a properly operating TPS2.
| Item | Detecting Condition | Possible Cause | |
| DTC Strategy | 
										•
									 Short to Ground or Open circuit | 1. Open in power supply harness or signal harness 2. Short to ground in power supply or signal harness 3. Poor connection or damaged harness 4. Faulty TPS2 | |
| Case1 | Enable Conditions | 
										•
									 Ignition "ON" | |
| Threshold Value | 
										•
									 TPS2 < 0.1V | ||
| Case2 | Enable Conditions | 
										•
									 Ignition "ON" 
										•
									 In idle status 
										•
									 Target throttle angle < 58% 
										•
									 MAF Limphome detected or TPS1 failure detected | |
| Threshold Value | 
										•
									 TPS2 at idle < 2.0V | ||
| Diagnostic Time | 
										•
									 0.05 sec. | ||
| MIL On Condition | 
										•
									 1 driving cycle | ||
| Limp-Home | 
										•
									 Forced limited power mode : When the DTC is set, the PCM reduces engine torque by 25% of normal value. 
										•
									 The PCM uses TPS1 signal to monitor the controlled opening angle of the throttle valve. | ||
