The EP-CAMS2605 is a complete camshaft synchronizer for the early-generation Ford 4.0L OHV Cologne V6 in Explorer (1993-1995), Ranger (1992-1995), and Aerostar (1995). The original Ford Motorcraft Cam Shaft Synchronizer DA-2077 / F37Z-12A362-A was discontinued and parts like F3TZ12K073A serve the 1992-1995 Ranger and Explorer 4.0L. This is the first generation of the Ford 4.0L cam synchronizer, predating the 1996 revised design that carries the F67Z-12A362 series numbers.

Compatible with Ford Aerostar 4.0L 1995, Explorer 4.0L 1993-1995, Ranger 4.0L 1992-1995. These early Explorer and Ranger 4.0L applications represent the beginning of Ford's extended use of the Cologne V6 in truck platforms -- a period when the synchronizer design was still being refined before the 1996 production update.

The EP-CAMS2605 is distinguishable from the later 1996+ units by its OEM reference (F3TZ vs F67Z) and the earlier-generation sensor housing design. Ships complete with cam position sensor and timing alignment tool.

Key features

Early 4.0L OHV V6 -- 1992-1995 generation

Covers the first generation of the Ford 4.0L Explorer and Ranger cam synchronizer, predating the 1996 design update that introduced the F67Z-12A362 series.

F3TZ-12K073-A -- the early Explorer/Ranger reference

OEM F3TZ-12K073-A is the primary Motorcraft reference for the 1992-1995 4.0L Explorer and Ranger synchronizer.

Discontinued OEM part -- aftermarket critical

The original Motorcraft DA-2077 for this application has been discontinued. Quality aftermarket supply (EP-CAMS2605) is the primary source for 1992-1995 owners.

1992-95 Ranger 4.0L cam synchronizer

Ranger 4.0L owners from the early Explorer/Ranger 4.0L era use EP-CAMS2605 for the correct early-spec unit.

Classic Ford 4.0L aftermarket supply

Parts distributors serving the 1992-1995 Explorer and Ranger 4.0L community stock EP-CAMS2605 as the aftermarket alternative to the discontinued OEM unit.

Installation guide

Confirm vehicle is 1992-1995 Explorer or Ranger (1993-1995 for Explorer, 1992-1995 for Ranger) with 4.0L OHV V6. The early-gen synchronizer has different dimensions from the 1996+ unit -- do not substitute CAMS2603 for this application. Set engine to TDC cylinder 1. Mark existing synchronizer orientation. Disconnect connector. Remove hold-down and old synchronizer. Install EP-CAMS2605 in same position. Use alignment tool to confirm rotor position. Tighten hold-down. Reconnect sensor. Clear fault codes.

Frequently asked questions

What is a camshaft synchronizer and how is it different from a distributor?
A camshaft synchronizer is a cam-driven position sensor assembly that replaced the traditional distributor on many Ford EFI engines of the 1990s. Like a distributor, it is driven by the camshaft and mounted in a similar location in the engine block -- but instead of routing high voltage to spark plugs, it contains a camshaft position sensor (CPS) that sends a digital signal to the EFI computer (ECM/PCM). The ECM uses this signal to precisely time fuel injection pulses and ignition firing. On these vehicles, ignition is handled by a separate coil-pack system, not by the synchronizer itself. The synchronizer provides only the camshaft timing reference signal -- but if this signal fails, the engine will not start or will run very poorly with CEL codes P0340, P0341, P0342, or P0343.
Does the EP-CAMS2605 ship with the cam position sensor and timing alignment tool?
Yes. The EP-CAMS2605 ships as a complete assembly including the synchronizer housing, the integrated camshaft position sensor pre-installed in the housing, and a timing alignment tool. The alignment tool is a C-shaped or window-type tool that clips onto the synchronizer during installation to confirm the rotor is positioned correctly relative to TDC before tightening the hold-down bolt. Using the alignment tool is critical -- reinstalling without it can result in a mistimed cam signal that causes immediate engine fault codes and poor running conditions. No additional components are required for direct OEM replacement.
Can the 1996 cam synchronizer (CAMS2603) be used in a 1993 Ford Explorer 4.0L?
No. The early-generation 4.0L synchronizer (CAMS2605, OEM F3TZ-12K073-A) and the 1996+ revised synchronizer (CAMS2603, OEM F67Z-12A362) have different housing dimensions, connector configurations, and drive designs. They are not interchangeable. Use EP-CAMS2605 for 1992-1995 Explorer and Ranger 4.0L applications, and EP-CAMS2603 for 1996-1998 applications.
What are the symptoms of a failing camshaft synchronizer?
The most common symptoms of a failing camshaft synchronizer include: Check Engine Light with diagnostic trouble codes P0340 (Camshaft Position Sensor Circuit Malfunction), P0341, P0342, or P0343; intermittent no-start conditions where the engine cranks but will not fire; rough or erratic idle quality; hesitation or stumbling under acceleration; poor fuel economy from incorrect injection timing; and stalling at operating temperature. The synchronizer seal can also fail, allowing oil to leak around the housing. On Ford 4.0L OHV V6 applications, the synchronizer is a known high-failure-rate component, and many mechanics recommend proactive replacement on high-mileage Explorer and Ranger 4.0L engines.
What is the difference between the 3-wire and 2-wire cam synchronizer on the Ford 4.0L?
The Ford 4.0L OHV V6 (Cologne engine) used two different cam synchronizer sensor connector configurations during production. Vehicles through approximately 1998 use a 3-wire connector (OEM F67Z-12A362-AA through AC revision). From 1999 onward, Ford revised the synchronizer to use a 2-wire connector (OEM XL5Z-12A362-AA). These two versions are NOT interchangeable -- the connectors, sensor circuit, and housing design differ between the 3-wire and 2-wire generations. Verify your vehicle's production year to determine which version you need: 1992-1998 4.0L applications use the 3-wire design; 1999-2000 applications use the 2-wire design. If uncertain, check the connector on your existing synchronizer before ordering.
How do I install the camshaft synchronizer correctly?
Correct installation of a camshaft synchronizer requires setting the engine to TDC (Top Dead Centre) on the number one cylinder compression stroke before removing the old synchronizer. Mark the position of the synchronizer housing and rotor on the old unit before removal so you can confirm the new unit goes in at the same orientation. After installing the new synchronizer, use the included alignment tool to verify the rotor position matches the correct timing mark before tightening the hold-down bolt. On Ford applications, the leading edge of the rotor's C-shaped vane must align with the timing mark visible through the synchronizer window when the engine is at TDC. Tighten the hold-down to factory torque specification. Failure to use the alignment tool results in a mistimed cam signal that immediately sets fault codes and causes rough running.
How do I order the EP-CAMS2605 for export or wholesale?
EP supports single-unit orders for market sampling, carton quantities for repair shops and parts counters, and container-volume wholesale orders. Standard production lead time is 15-30 days. OEM branding and private-label packaging are available for qualifying volumes. Contact our team via the inquiry form or WhatsApp for pricing and availability.
