1997 Dodge Ram 1500 - P0713 Transmission Fluid Temperature Sensor Issue: Diagnosis and Solutions

Model: 97 Ram 1500 Fault Code: P0713 Posted: 2006-08-31 15:06

I'm experiencing a persistent P0713 fault code on my 1997 Dodge Ram 1500, indicating a high input from the transmission fluid temperature sensor. I've tried multiple troubleshooting steps, but the issue keeps returning. The vehicle seems to operate normally, and there are no obvious symptoms—yet the check engine light remains on with this specific code. What should be my next step in diagnosing this problem? Any guidance or common causes for P0713 in a 1997 Ram 1500 would be greatly appreciated.

Have you checked the wiring harness connected to the transmission? Also, has the valve body been inspected for any internal issues?

No, I haven't. The truck runs fine and there are no noticeable performance problems—so what exactly should I look for in terms of symptoms or diagnostics?

It's important to verify the electrical circuit is functioning properly—check if the transmission sensor signal is being correctly received by the Powertrain Control Module (PCM). If the signal is present, a faulty valve body could be the root cause.

I own a 1996 Dodge B2500 with a 5.2L V8 engine and was experiencing severe transmission issues. After using an OBD-II scanner, I got P0713—however, dealerships and parts stores claimed this code doesn't exist for my vehicle. It took me two months to resolve the issue. Eventually, I found the root cause, but the code still persists. My truck started having problems again after a year. A CHP recently told me about a device called a 'Scan Gauge' that plugs into the same OBD-II port as standard scanners. This tool provides real-time readings of all parameters—including voltage and temperature—rather than just detecting failure. It can show if a sensor is reading incorrectly, even if it's not failing outright. The CHP will loan me one next week. OBD-II only flags issues when components are actually faulty; for example, if the battery reads 4V, OBD won't detect it because there’s still voltage present—only when it drops to zero does it register a failure. A Scan Gauge shows actual values and can help identify early problems. It costs around $100. Do you have any similar issues with your vehicle? Any updates on your current situation?

sportsterdaddy, please start a new thread—do you know the exact transmission type? List all diagnostic codes (including any P1xxx manufacturer-specific codes). Describe other issues such as performance problems or electrical malfunctions. Also, mention any modifications like remote starters, alarms, or aftermarket electronics.
