Conditions for Clearing the DTC

WARNING: This page is about a different variant/trim than selected.

A current DTC Last Test Failed clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic.
Clear the DTC with a scan tool.

DTC P2135

Step	Action	Values	Yes	No
Schematic Reference: Engine Controls Schematics Connector End View Reference: Engine Control Module (ECM) Connector End Views or Engine Controls Connector End Views
1	Did you perform the Diagnostic System Check-Engine Controls?	-	Go to Step 2	Go to Diagnostic System Check - Engine Controls
2	Observe the DTC information with a scan tool. Is DTC P0101, P0121, P0122, P0123, P0221, P0222, P0223, P2122, P2123, P2127, P2128 also set?	-	Go to Diagnostic Trouble Code (DTC) List	Go to Step 3
3	Turn OFF the ignition. Disconnect the throttle position (TP) sensor electrical connector. Refer to Throttle Body Assembly Replacement . Disconnect the engine control module (ECM). Refer to Engine Control Module (ECM) Replacement . Measure the resistance of the following circuits with a DMM for each of the TP sensors: The low reference circuit The TP sensor signal circuit The 5-volt reference circuit Is the resistance more than the specified value for any circuit?	5 ohm	Go to Step 7	Go to Step 4
4	Test the signal circuit of the TP sensor 1 for a short to the signal circuit of TP sensor 2. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 9	Go to Step 5
5	Test for an intermittent and for a poor connection at the TP sensor. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 9	Go to Step 6
6	Test for an intermittent and for a poor connection at the ECM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 9	Go to Step 8
7	Repair the high resistance in the circuit that measured above the specified value. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair?	-	Go to Step 9	-
8	Replace the throttle body assembly. Refer to Throttle Body Assembly Replacement . Did you complete the replacement?	-	Go to Step 9	-
9	Clear the DTCs with a scan tool. Turn OFF the ignition for 30 seconds. Start the engine. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition?	-	Go to Step 2	Go to Step 10
10	Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List	System OK
