Stratus V6-2.5L VIN H (1997)
8.
Disconnect the powertrain control module C1 connector (Figure 2). Unwrap the tape as required to expose the insulation 3 to 4 inches behind the
connector.
9.
Remove the wire dress cover from the rear of the C1 connector. Locate cavity 43 of the connector (K4 circuit BK/LB, Figure 2).
10.
Cut the k4 wire 1-1/2 inches from the C1 connector. Strip both ends of the cut wire and the end of the new lead.
11.
Slip a piece of heat shrink tube p/n 04778570 over the lead connected to the C1 connector. Make sure the shrink tube is long enough to seal the
splice after soldering.
12.
Twist all three leads together and solder the splice with rosin core solder. Slide the heat shrink tube over the splice and shrink with a heat gun until
sealant flows from both ends of the shrink tubing.
13.
Reinstall the wire dress cover to the rear of the C1 connector. Using electrical tape p/n 04778138, tape over the repaired area to match the original
construction of the harness finishing the tape on the tape flange of the wire dress cover.
14.
Reconnect the oxygen sensor to its harness and the C1 connector to the powertrain control module.
15.
Reconnect the battery negative cable.
16.
Verify the wiring repair by running the oxygen sensor test with the DRB III.
Double Upstream 02 Sensor
1.
Disconnect the battery negative lead.
2.
Locate the upstream oxygen sensor connector # 1 and disconnect it.
3.
Identify the sensor ground terminal. For 1995 models, it is terminal # 1, K4 circuit, 18 gauge black with a light blue tracer (Figure 1).
4.
1995 connectors use a front loaded secondary lock wedge connector. Remove the lock wedge by using a paper clip as a hook. Remove terminal #
1 by depressing the connector lock finger with a terminal pick or paper clip while pulling the terminal out form the rear.
5.
Choose the terminal on the end of the repair lead p/n 05010934AA that has the longer length of wire from the Y splice (1100 mm). Insert the new
terminal and wire lead into the vacant cavity of the oxygen sensor connector. Assemble the connector by reversing the connector disassembly
procedure.
6.
Fold the removed oxygen sensor terminal onto itself and place a piece of heat shrink tubing p/n 04778570 over the wire end. Shrink with a heat
gun until sealant flows from both ends. Tape the removed wire out of the way.
7.
Repeat steps 3 through 6 for the upstream oxygen sensor No. 2, using the other lead from the Y spliced repair jumper.
8.
Tape wrap the new lead neatly to the wiring harness and route it up to the powertrain control module.
9.
Disconnect the powertrain control module C1 connector (Figure 2). Unwrap the tape as required to expose the insulation 3 to 4 inches behind the
connector.
10.
Remove the wire dress cover from the rear of the C1 connector. Locate cavity 43 of the connector (K4 circuit BK/LB, Figure 2).
11.
Cut the K4 wire 1-1/2 inches from the C1 connector. Strip both ends of the cut wire and the end of the new lead.
12.
Slip a piece of heat shrink tube p/n 04778570 over the lead connected to the C1 connector. Make sure the shrink tube is long enough to seal the
splice after soldering.
