I scanned my van and the DTC P0202 showed up I printed some of the diagnostic information from my job but forgot to print the resst of the test information. I printed "Test TC-21A but it left me asking me to perform diagnostic test "TC-20A" and I don't have the proceedure, can you help?

TEST TC-20A - INJECTOR NO. 2 CONTROL CIRCUIT
1. Ensure ignition is off. Disconnect connector at injector No. 2. It may be necessary to remove air intake plenum for access to connector at injector No. 2.

2. Injector No. 2 is the first injector back from front (timing belt end) of engine on left side when viewed from flywheel end of engine.

3. Using ohmmeter, check resistance between electrical terminals on injector No. 2. If resistance is 10-16 ohms, go to next step. If resistance is not 10-16 ohms, replace injector. Perform TEST VER-2A.

4. Turn ignition on. Using scan tool, actuate Auto Shutdown (ASD) relay. Using voltmeter, check voltage at terminal No. 2 (Dark Green/Orange wire) on connector for injector No. 2.

5. If voltage cycles from high voltage to low voltage, go to next step. If voltage does not cycle from high voltage to low voltage, repair open circuit in Dark Green/Orange wire between injector No. 2 and ASD relay. Perform TEST VER-2A. The ASD relay is located in power distribution center at driver's side front corner of engine compartment, near battery.

6. Turn ignition off. Disconnect connectors from Powertrain Control Module (PCM). The PCM is located between driver's side front fender and power distribution center, near battery.

7. Using ohmmeter, check resistance between ground and PCM connector terminal No. 17 (Tan wire). If resistance is less than 5 ohms, repair short to ground in Tan wire between PCM and injector No. 2. Perform TEST VER-2A. If resistance is 5 ohms or more, go to next step.

8. Using ohmmeter, check resistance between terminal No. 1 (Tan wire) on connector for injector No. 2 and PCM connector terminal No. 17 (Tan wire). If resistance is 5 ohms or more, repair open circuit in Tan wire between PCM and injector No. 2. Perform TEST VER-2A. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2A.
