APRILIA RSV4 Factory a-PRC 2009 User Manual

•
Example value with engine on: 25° C
•
The temperature value is stored during engine start-up. With key ON, value -40°C is read.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL TROU-
BLESHOOTING CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGINNING OF THE CHECK
AND CONTROL SECTION IN THE ELECTRICAL SYSTEM CHAPTER.
DIAGNOSTICS INSTRUMENT: ELECTRICAL ERRORS
engine temperature sensor P0115
•
open circuit, shorted to positive / shorted to negative.
Error cause
•
If the circuit is open, shorted to positive: excessive voltage has been detected at PIN 12 of
the ENGINE connector. If shorted to negative: voltage equal to zero has been detected. The
instrument panel does not indicate the presence of this error even in the ATT status.
Troubleshooting
•
If the circuit is open, shorted to positive: check the sensor connector and the Marelli control
unit connector. If they are OK, check sensor continuity: replace the sensor if not OK; if OK,
check continuity between the ENGINE connector PIN 12 and the sensor PIN 1: restore cable
harness if there is not continuity; if it is OK, reconnect the control unit connector and, with
key set to key ON, check the continuity between the sensor connector PIN 2 and the vehicle
ground connection: if OK, it means that the error cause is that the cable is shorted to positive
and it is necessary to restore the cable harness between ENGINE PIN 12 and sensor PIN
1; if there is no continuity with the ground connection, check the sensor connector and the
Marelli control unit connector. If not OK, restore the cable harness. If OK, check continuity
between the ENGINE connector PIN 6 or 17 and the sensor connector PIN 2: restore the
cable harness if there is not continuity. If there is, it means that the control unit does not
supply the ground connection and therefore should be replaced.
•
If shorted to negative, check sensor correct resistance: if resistance is null, replace the sen-
sor; if resistance is correct, it means that the Yellow/Brown cable has ground connection:
restore the cable harness
DIAGNOSIS INSTRUMENT: LOGIC ERRORS
engine temperature sensor P0116
•
signal not valid.
Error cause
•
An excessive temperature variation has been detected: for example, the cause may be a
contact resistance between the terminals. The instrument panel does not indicate the pres-
ence of this error even in the ATT status.
