While it is a generic code, the specific repair steps may vary depending on the make and model of the vehicle. If you find that a code P has been stored in your OBD-II vehicle, it means that the powertrain control module PCM has detected a malfunction in a specific circuit related to the torque converter brake switch. This code is only applicable to vehicles equipped with automatic transmissions. Automatic transmissions in mass-produced vehicles have been electronically controlled since the s. Other vehicles use a separate transmission control module that communicates with the PCM and other controllers via the controller area network CAN. The torque converter is a type of fluid coupling that connects the engine to the transmission. When the vehicle is in motion, the torque converter transfers torque to the transmission input shaft. This allows the engine to idle without stalling. The lockup torque converter, used in OBD-II equipped vehicles, allows the engine to lock into the transmission input shaft under certain conditions. This typically occurs when the transmission has shifted into the highest gear, the vehicle has reached a certain speed, and the desired engine RPM level has been achieved. In lockup mode, the torque converter clutch TCC gradually restricts until the transmission functions as if it were directly connected to the engine in a transfer ratio. These gradual clutch restrictions are referred to as the percentage of torque converter lockup. This system promotes fuel efficiency and optimal engine performance. Torque converter lockup is achieved using an electronic solenoid that controls a spring-loaded rod or ball valve. When the PCM recognizes that conditions are correct, the lockup solenoid is activated, allowing fluid to bypass the torque converter gradually and be applied directly to the valve body.

Ok any idea on how I can rule them out? This typically occurs when the transmission has p0703 ford into the highest gear, the vehicle has reached a certain speed, and the desired engine RPM level has been achieved, p0703 ford. Recommended Communities.

Does anyone have any ideas on this? Could it be the pressure switch under the master cylinder? Or is it the switch on the brake pedal? The Ford dealer told me that switch is adjustable.

Symptoms may include the inability to shift out of park or the brake lights not functioning properly. The cause could be a faulty BPP switch, a misadjusted switch, an open or shorted circuit, or a poor electrical connection. To fix the issue, visually inspect the wiring harness and connectors for any damage. Look for broken, bent, pushed out, or corroded pins on the connectors.

He was wrong!!! Failure to do so will result in the engine stalling. P brake switch B circuit fault. Email this Page. I messed up misfire monitor 54 fail. A "normal" misfire count for a well-running engine would be zero. Bluegrass 7. Quote message in reply? Lightning Owners Forum. When the brake pedal is applied, the brake lever arm closes contacts in the brake switch, completing one or more circuits. So my scanner pick up P, and from what I read real quick it also has something to do with the torque converter, diminished fuel efficiency, loss of power highway speeds, erratic trans shift patterns.

The P code on the 6. So, what should you do if you see the P code? To help you out, in this article, we will discuss what this code means, its symptoms, and how to fix it.

If the RPM level increases when the brake is depressed, the TCC is operational and the brake switch is deactivating it properly Failure of the TCC system to operate can cause major transmission damage Professional Service While we always recommend seeking mechanical solutions for this issue, if that is not possible, we offer the option to permanently delete this specific DTC.
