DTC 22 2
UnclassifiedFuel
What This Code Means
TPS 2 Signal Voltage Low; TPS2 voltage < 1.00 VDC at 0% TPS; DST displays TPS2 voltage <0.2 VDC with the throttle closed; DST displays TPS2 voltage <0.2 VDC with the throttle open; TPS2 voltage falls below 0.2 volts when releasing FPP sensor
Possible Causes
- •Intermittent Problem
- •Poor Throttle Connection
- •Faulty Throttle
Suggested Actions
- 1Perform the On-Board (OBD) System Check.
- 2Key ON, Engine OFF, set System Mode to 'Stopped', enable 'DBW Test' mode, and check if TPS2 voltage is low (< 1.00 VDC) at 0% TPS.
- 3Observe if DST displays TPS2 voltage <0.2 VDC with the throttle closed.
- 4Slowly depress FP (or sweep throttle on stationary applications by typing the desired throttle opening % in the TPS Command box on the DBW page) and observe if DST displays TPS2 voltage <0.2 VDC with the throttle open.
- 5Key OFF and disconnect throttle from harness.
- 6Slowly release FPP sensor while observing if TPS2 voltage falls below 0.2 volts.
- 7Jumper 5Vref1 to TPS2 signal circuit at throttle connector, set Key On, Engine Off, System Mode = 'Stopped', and check if DST displays TPS2 voltage >4.0 VDC.
