Honda Element. Manual — part 39

Fig. 107: Vehicle Speed Graph

General Description

The output shaft (countershaft) speed sensor is attached to the outside of the transmission housing. The output
shaft (countershaft) speed sensor generates a pulsing signal according to the speed of the park gear on the output
shaft (countershaft). Using that signal, the powertrain control module (PCM) determines the speed of the output
shaft (countershaft). If pulse dropouts occur with the output shaft (countershaft) rotating, the PCM detects a
malfunction that may be caused by an open, a temporary open, or a short to ground. Based on the correlation
between the vehicle speed measured by the output shaft (countershaft) speed sensor and the input shaft
(mainshaft) speed sensor, a malfunction is detected and a DTC is stored.

Malfunction Threshold

When the vehicle speed measured by the input shaft (mainshaft) speed sensor is 13 mph (20 km/h) or more, the
vehicle speed measured by the output shaft (countershaft) speed sensor is 1 mph (2 km/h) or less for at least 10
seconds.

2007 ENGINE PERFORMANCE Advanced Diagnostics - Element

Start the engine, and drive the vehicle at a speed of 13 mph (20 km/h) or more for at least 10 seconds.



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the
PCM memory.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by
disconnecting the battery.

General Description

The output shaft (countershaft) speed sensor is attached to the outside of the transmission housing. The output
shaft (countershaft) speed sensor generates a pulsing signal according to the speed of the park gear on the output
shaft (countershaft). Using that signal, the powertrain control module (PCM) determines the speed of the output
shaft (countershaft). If pulse dropouts occur with the output shaft (countershaft) rotating, the PCM detects a
malfunction that may be caused by an open, a temporary open, or a short to ground. Based on the fluctuation of
the vehicle speed measured by the output shaft (countershaft) speed sensor, a malfunction is detected and a
DTC is stored.

Malfunction Threshold

The fluctuation of the vehicle speed measured by the output shaft (countershaft) speed sensor in 10 milliseconds
is 4 mph (6km/h) or more, and it fluctuates at least six times within 500 milliseconds.

Driving Pattern

Start the engine, and drive the vehicle at a speed of 13 mph (20 km/h) or more so it shifts from 1st to 5th in D
position.



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the PCM memory. If
the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the freeze
frame data are stored.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool Clear
command or by disconnecting the battery.
