INSPECTION

PROCEDURE

1. INSPECT COLUMN SHIFT SHIFT LEVER SUB-ASSEMBLY

(a) Disconnect the transmission control switch connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
6 (IG) - 13 (S)	Shift lever in S, "+" or "-"	Below 1 Ω
5 (SFTU) - 11 (E)	Shift lever held in "+" (Up-shift)
4 (SFTD) - 11 (E)	Shift lever held in "-" (Down-shift)
6 (IG) - 13 (S)	Shift lever not in S, "+" or "-"	10 kΩ or higher
5 (SFTU) - 11 (E)	Shift lever in S
4 (SFTD) - 11 (E)	Shift lever in S

If the result is not as specified, replace the column shift shift lever sub-assembly.

Toyota Tundra Service Manual > Automatic Transmission System: Shift Solenoid "B" Performance (Shift Solenoid Valve S2) (P0756)
DESCRIPTION The ECM uses signals from the output shaft speed sensor and input speed sensor to detect the actual gear position (1st, 2nd, 3rd, 4th, 5th or 6th gear). Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical problems of the shift solenoid val ...
