2014-2016 Transit Connect
ISSUE:
Some 2014-2016 Transit Connect vehicles equipped with 2.5L engine may exhibit an intermittent condition in which the ambient air temperature (AAT) display in the instrument panel cluster (IPC) is inaccurate and/or the A/C is inoperative. The inoperative A/C may be caused by the AAT reading below -1.1 °C (30 °F) the actual ambient temperature is above -1.1 °C (30 °F) with diagnostic trouble codes (DTCs) P0073, P0074 and/or U0422.
ACTION:
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Does the AAT display in the IPC read inaccurate and/or the AAT temp reading is below -1.1 °C (30 °F) with A/C inoperative?
(1). Yes – proceed to Step 3.
(2). No – proceed to Step 2.
2. Connect the Ford Integrated Diagnostic System (IDS) service tool or equivalent scan tool to the data link connector (DLC). Check for DTCs and historical powertrain DTCs. Are DTCs U0422 stored in the IPC and/or P0073 and/or P0074 stored in the powertrain control module (PCM) memory or in the historical powertrain DTCs snapshot data?
(1). Yes – proceed to Step 3.
(2). No – this article does not apply. Refer to Powertrain Control/Emissions Diagnosis (PC/ED) manual for normal diagnostics.
3. Using IDS, reset the keep alive memory (KAM).
4. Is the AAT display in the IPC display accurate and does the A/C resume function?
(1). Yes – replace AAT sensor. Refer to Workshop Manual (WSM), Section 412-00 and proceed to Step 5.
(2). No – this article does not apply. Refer to PC/ED manual for normal diagnostics.
5. Replace the AAT sensor connector using the pigtail connector kit.
(1). Disconnect the negative battery cable. Refer to WSM, Section 414-01.
(2). Take the AAT sensor connector pigtail from the connector kit and cut to size.
- The overall length should not exceed 15 cm (6″). Take measurement from the back of the AAT sensor connector to the middle of the harness node. (Figure 1A)
(3). Use Rotunda Coroplast™ electrical wire harness tape or equivalent. Wrap 15 cm (6″) length of wire of the pigtail harness. Leave enough wire from the pigtail exposed to splice it to the main harness. (Figure 1)
(4). Fold back the AAT sensor connector harness so that 17 mm (5/8″) of wire is bent from the back of the connector and 17 mm (5/8″) of wire is bent from the front of the connector. (Figure 2A)
(5). Use a half-width piece of electrical tape and tape the harness to the connector.
- Avoid taping over the locking tab of the connector.
(6). Remove and save the wiring convolute from the engine wiring harness and cut the AAT sensor connector wires 10 mm (3/8″) away from the connector on the engine harness. Cut each circuit individually.
(7). Refer to the instructions in the AAT sensor connector pigtail kit for installation.
(8). Take the saved convolute from Step 5f and cut a length approximately 60 mm (2 3/8″). Install the convolute over the new AAT sensor connector harness. (Figure 1B)
(9). Using Rotunda Coroplast™ electrical wire harness tape or equivalent electrical tape, tape under the convolute first and leave 10 mm (3/8″ ) of the tape beyond the convolute, then tape over the convolute starting at the end nearest to the connector back to the harness. (Figure 3)
- Avoid taping over the locking tab of the connector.
6. Connect the new connector to the AAT sensor. Refer to WSM, Section 412-00.
7. Connect the negative battery terminal. Refer to WSM, Section 414-01.
