P2803 - TRANSMISSION RANGE SENSOR B CIRCUIT HIGH
| Description: | The powertrain control module (PCM) checks the gear selector position by monitoring two independent voltage signals from the transmission range (TR) sensor. The TR voltages are then compared to an allowed voltage range for each gear. The test fails when the compared voltages are out of range. This DTC indicates that one TR signal is high. | ||
