P1700

Scope: 2.2D · System(s): EMS/diesel

Common causes

• Transmission/ECU communication or configuration issue
• can accompany injector/DPF problems

Quick checks

• Confirm freeze-frame and conditions when the code set
• Compare live sensor values vs expected (unplugged/biased sensors are common)
• Swap coil/plug to another cylinder if misfire is cylinder-specific
• Check module power/grounds and bus wiring before condemning a module

Typical fixes

• Read all module codes with Jaguar-capable diagnostics
• diagnose the root module fault rather than replacing the transmission from this code alone.
