The Nissan throttle position sensor collects data on how hard you’re pushing the gas pedal, then relays this information to the ECU so it can tell the TCM which shift program to use, and what gear the transmission should be in. A P1705 OBDII trouble code means that there is either a short in the circuit, or the throttle position sensor itself has failed.
How Serious is the Code?
A Nissan P1705 diagnostic trouble code is actually quite serious, and the driver can experience a number of transmission problems that range from a hesitation to shift, poor acceleration and engine stalling.
Symptoms of a P1705 include:
- Poor acceleration
- Vehicle seems to the jerk when the gas pedal is depressed
- Surging RPMs
- Unintended sudden acceleration surges
- Erratic transmission behavior
- Engine stalling
- Short in the throttle position sensor wiring
- Short in the CAN bus circuit
- Throttle position sensor has failed
How to Diagnose the Code?
In order to diagnose a P1705 OBD2 code, a trained technician will need to connect a scan tool to the OBDII port, then analyze the data after driving it at the prescribed speeds, according to the Nissan diagnostic procedure.
