DTC 222

UnclassifiedFuel

What This Code Means

MIL ON during active fault; Engine Shutdown; Malfunction Indicator Light (MIL) ON during active fault; TPS2 voltage low (< 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 VDC

Possible Causes

  • •TPS1 voltage is greater than 4.8V or less than 0.2V AND TPS2 voltage is greater than 4.8V or less than 0.2V
  • •Simultaneous voltage out-of-range faults for both TPS 1 and TPS2
  • •Throttle Position Sensor (TPS) failure
  • •TPS 2 sensor voltage less than 0.200 volts
  • •Intermittent Problem
  • •Poor Throttle Connection
  • •Faulty Throttle

Suggested Actions

  1. 1Replace the electronic throttle assembly
  2. 2Troubleshoot according to TPS1 voltage out-of-range following DTC 122 and 123 procedures
  3. 3Troubleshoot according to TPS2 voltage out-of-range following DTC 222 and 223 procedures
  4. 4Perform the On-Board (OBD) System Check
  5. 5With Key ON, Engine OFF, System Mode 'Stopped', enable 'DBW Test' mode and check if TPS2 voltage is < 1.00 VDC at 0% TPS by design
  6. 6Slowly depress FP while observing TPS2 voltage (or sweep throttle on stationary applications using DBW page TPS Command box)
  7. 7Turn Key OFF and disconnect throttle from harness
  8. 8Slowly release FPP sensor while observing TPS2 voltage
  9. 9Jumper 5Vref1 to TPS2 signal circuit at throttle connector, turn Key ON, Engine OFF, System Mode 'Stopped' and check if DST displays TPS2 voltage >4.0 VDC
