Test TC-32A - Injector #5 Control CKT (Injectors No. 2 & 7) (DTC 27)
WARNING: This page is about a different car, the 1995 Dodge Pickup and 1995 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION

section at the end of this article.
- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using an external ohmmeter, check resistance between PCM terminals No. 57, ASD relay output circuit (Dark Green/Orange wire) and No. 58, injector No. 5 driver circuit (Light Green/Black wire) and If resistance is 6-18 ohms, replace PCM. Perform TEST VER-2.
- If resistance is not 6-18 ohms, using scan tool in ohmmeter mode, check resistance of PCM terminal No. 58, injectors No. 2 and 7 driver circuit (Light Green/Black wire). If resistance is more than 5 ohms, repair open Light Green/Black wire. Perform TEST VER-2.
- If resistance is less than 5 ohms, disconnect injector No. 2 connector. Check resistance of PCM terminal No. 58, injectors No. 2 and 7 driver circuit (Light Green/Black wire). If resistance is more than 5 ohms, replace injector No. 2. Perform TEST VER-2.
- If resistance is less than 5 ohms, disconnect injector No. 7 connector. Check resistance of PCM terminal No. 58, injectors No. 2 and 7 driver circuit (Light Green/Black wire). If resistance is more than 5 ohms, replace injector No. 7. Perform TEST VER-2. If resistance is less than 5 ohms, repair short to ground in Light Green/Black wire. Perform TEST VER-2.
