Conditions for Setting the DTC

P0121 

The ECM detects that the throttle position sensor input is stuck within normal operating range for greater than 178 ms.

P0122 

The ECM detects the throttle position sensor 1 signal voltage is less than 0.33 V for greater than 178 ms, or for 247 ms of a 497 ms time frame.

P0123 

The ECM detects the throttle position sensor 1 signal voltage is greater than 4.75 V for greater than 178 ms, or for 247 ms of a 497 ms time frame.

P0222 

The ECM detects the throttle position sensor 2 signal voltage is less than 0.25 V for greater than 178 ms, or for 247 ms of a 497 ms time frame.

P0223 

The ECM detects the throttle position sensor 2 signal voltage is greater than 4.59 V for greater than 178 ms, or for 247 ms of a 497 ms time frame.

P16A0 

The ECM detects a low voltage circuit condition on the throttle position sensor signal circuit for greater than 178 ms, or for 247 ms of a 497 ms time frame.

P16A1 

The ECM detects a high voltage circuit condition on the throttle position sensor signal circuit for greater than 178 ms, or for 247 ms of a 497 ms time frame.

P16A2 

The ECM detects an incorrect message was received over the throttle position sensor signal circuit for greater than 178 ms, or for 247 ms of a 497 ms time frame.

P2135

• The ECM detects that throttle position sensors 1 and 2 disagree greater than 7 % at minimum throttle, with a linear threshold to 10 % at wide open throttle (WOT).

  OR

• The ECM detects that the TP sensor 1 and 2 learned minimum throttle position voltages is greater than 5 percent of the 5 volt reference voltage.
• Either condition exists for greater than 181 ms, or for 247 ms of a 497 ms time frame.
