The hydraulic pressure May 6, 2020 · Re: 68RFE Transmission P0740/P0933/P0935 Looks like these codes are common with a line pressure sensor fault. Clean it up if needed and then reconnect. If left unaddressed, it can cause permanent damage to your transmission. It does this with the pressure control solenoid (s), but the decision is made using data from the hydraulic pressure sensor. If the sensor sends back an implausible signal, code P0933 is stored. Jul 31, 2021 · I get this 0933 code bout every 5-10 days. What causes the P0933 Engine Error Code? Aug 11, 2025 · The P0933 code is an OBD-II trouble code that indicates a problem with the hydraulic pressure sensor in the vehicle’s transmission system. This could be due to a malfunctioning sensor or issues in the associated wiring or connectors, which can disrupt the transmission’s ability to regulate hydraulic pressure accurately. The LP sensor is at the very rear end of the main transmission case, on the passenger side, just above the oil pan rail. Anyone have experience chasing this one down? I've replaced sensor and the plug that connects to it. Its seems to be intermittent. Now I won’t shift out of 1st gear it’s in limp mode I replaced the transmission pressure sensor, the filter and fluid still have the same issue. The subject is a rather common electrical fault that may occur on the PCS line pressure solenoid circuit, which results in max line pressure. The P0933 diagnostic trouble code (DTC) indicates that there is an issue with the hydraulic pressure sensor's range or performance in the vehicle's transmission system.
