Fault Code Description Definition
P0221
Electrical throttle position sensor
signal 2 unreasonable
• ECM provides 5V reference voltage to terminal 3
of TPS sensor wiring harness connector E23
through terminal 32 of wiring harness connector
E01.
• TPS provides sensor signal voltage to terminal 38
of ECM wiring harness connector E01 through ter-
minal 5 of E23.
• ECM positions terminal 2 of TPS sensor wiring
harness connector E23 at low electrical potential
through terminal 78 of wiring harness connector
E01.
P0222
Electrical throttle position sensor
signal 2 circuit voltage too low
P0223
Electrical throttle position sensor
signal 2 circuit voltage too high
