The rule of P0705 Toyota Hilux code when it comes to emissions-related vehicle repair is that any modification that changes the vehicle from a certified configuration to a non-certified configuration is considered tampering: this applies to both vehicle owners and repair facilities and is, therefore, a Federal offense. Replacing a catalyst with a straight pipe is one traditional example of P0705. P0705 Toyota Description The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM).
DESCRIPTION
The Park/Neutral Position (PNP) switch detects the shift lever position and sends signals to the ECM.
DTC Code | DTC Detection Condition | Trouble Area |
---|---|---|
P0705 | One of the following conditions is met: (A) Any 2 or more of the following signals are ON simultaneously (2-trip detection logic):
(B) Any of the following signals is ON for 2.0 sec. or more with the shift lever in S (2-trip detection logic):
(C) All switches are OFF simultaneously for P, R, N, D and NSW (2-trip detection logic). |

MONITOR DESCRIPTION
This DTC indicates a problem with the park/neutral position switch and wire harness in the park/neutral position switch circuit.
The park/neutral position switch detects the shift lever position (P, R, N, D or S) and sends a signal to the ECM.
For security, the park/neutral position switch detects the shift lever position so that the engine can be started only when the shift lever is in P or N.
The ECM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The ECM will illuminate the MIL and store the DTC.

1. DATA LIST
HINT:
Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
NOTICE:
In the table below, the values listed under 'Normal Condition' are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch off.
Keygen office 2016 for mac. (c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Enter the following menus: Powertrain / Engine and ECT / Data List.
(g) According to the display on the Techstream, read the Data List.
