Dodge Caravan P0700 Code: Can a Burnt Solenoid Cause This Transmission Error?

Model: dodge caravan Fault Code: P0700 Posted: 2015-09-18 14:35

Can a burnt solenoid cause a P0700 diagnostic code in a Dodge Caravan? The P0700 code is a generic transmission-related trouble code that indicates an issue within the transmission control module (TCM) or transmission system. While it's not specific to one component, potential causes include faulty power supply, relay failure, TCM malfunction, solenoid pack issues, speed sensors, or worn clutches. A burnt solenoid is a plausible contributor, especially if the transmission fails to shift properly or enters limp mode—such as staying in second gear or refusing to shift at all. To diagnose accurately, a scan tool capable of reading TCM-specific transmission codes is essential. Even when no warning light is visible, the P0700 code may still be stored internally. Addressing this issue requires identifying the root cause through proper diagnostic tools and vehicle-specific data.

Which solenoid do you suspect? The P0700 code is a broad transmission fault that can be triggered by issues such as a non-energized trans relay, faulty fuse, or remote starter malfunction. More specific details about the vehicle (year, model, trim) would help narrow down potential causes.

P0700 indicates that the transmission control module (TCM) has detected a problem in the transmission system. Possible root causes include power supply issues, relay failure, TCM faults, solenoid pack malfunction, speed sensor errors, or worn clutches. A dedicated scan tool is required to retrieve TCM-specific transmission codes. Once set, the vehicle may enter limp mode—limiting shifts and possibly defaulting to second gear until the issue is resolved.

I'm confused but here's my situation: I have a 2001 Dodge Caravan with no check engine light. I've already replaced input and output speed sensors. The speedometer behaves erratically—sometimes showing speeds up to 120 mph when the car is stationary, and it occasionally cuts out completely. A mechanic suggested I might need a catalytic converter (likely a typo—should be 'catalytic converter'), but I'm not sure if that's relevant. I previously recorded around 12 codes, but can't find them now. When parked, my speedometer reads 120 mph intermittently. Can anyone help me troubleshoot this? Thank you. Sherree

Visit most auto parts stores for a free diagnostic scan—write down all codes even if the check engine light is off. A speedometer reading 120 mph when stationary is often linked to an alternator issue, particularly faulty diodes—not just low voltage output. Always inspect diode health in addition to DC voltage. Note: The term 'catalytic converter' was mentioned, but there's no indication it’s the root cause based on your symptoms. A proper scan tool and detailed diagnostics are key.
