DTC P2135
General Information
Read this general information to better understand what can set code P2135 in the ECM. After
the general information, you will find information about possible root causes and tips for diagnosing
and repairing affected vehicles.
NOTE
Throttle Position Sensor circuit codes such as P0120, P0220, P0122, P0123, P0222 or P0223,
should take diagnostic priority over a P2135 code. If any of these TP sensor codes exist concurrently
with the P2135, they should be investigated first using the Electrical Diagnostic Manual.
The two TP sensors work opposite of each other. As the throttle plate opens, TPS1 voltage ranges
from 0.0-5.0V, while TPS2 voltage ranges from 5.0-0.0V.The sum of the two TPS voltages should
always measure approximately 5.0V. These wires are: TPS1, BN/V pin 37 of the ECM, and TPS
BN/R pin 36 of the ECM.
The TP sensors 1 and 2 should never add to more than 5.13 VDC or less than 4.87 VDC. A sum
of voltages out of this range should register a current P2135 code.

What is the procedures for checking codes??

What is the procedures for checking codes??

You can access the codes through the speedometer/odometer, see the following thread for the procedure.

Scroll down to reply number 4.  This information is also in the manuals, at least how to enter the self diagnosis mode.  You would need the Electrical manual to get all the actual codes and details for each.
