Conditions for Clearing the DTC

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

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 Controls Connector End Views or Engine Control Module Connector End Views
1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Observe the DTC Information with a scan tool. Is DTC P0120 or P0220 also set?	-	Go to Diagnostic Trouble Code (DTC) List - Vehicle	Go to Step 3
3	Turn OFF the ignition. Disconnect the throttle body harness connector. Disconnect the engine control module (ECM) harness connector. Measure the resistance of the following circuits for each of the throttle position (TP) sensors with a DMM: The low reference circuit The signal circuit The 5-volt reference circuit Is the resistance more than the specified value for any circuit?	5 Ω	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 the TP sensor 2. Refer to Circuit Testing and Wiring Repairs . 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 throttle body harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . 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 harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . 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 . Did you find and correct the condition?	-	Go to Step 9	-
8	Replace the throttle body. 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	IMPORTANT: Be aware that repairing one individual condition may correct more than one DTC. Observe the Capture Info with a scan tool.Are there any DTCs that have not been diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List - Vehicle	System OK
