P1125
TPS1
TPS1 signal missing. Acknowledge-
ment occurs when the signal voltage is
close to:
0V = short circuit
5V = open circuit
Free On
P1128
TPS2
TPS2 signal missing. Acknowledge-
ment occurs when the signal voltage is
close to:
0V = short circuit
5V = open circuit
Free On
P1120
TPS OFFSET
The voltage of both TPS signals in not
as expected. The fault is recognised by
comparing the signals with the power
supply polarity
Stays idle On
P1124
TPS1OFFSET
The voltage of TPS1 signal in not as ex-
pected. The fault is recognised by com-
paring the signals with the TPS1 power
supply polarity
Free Off
P1127
TPS2
The voltage of TPS2 signal in not as ex-
pected. The fault is recognised by com-
paring the signals with the TPS2 power
supply polarity
Free Off

SENSOR
VOLTAGE
The TPS sensor and coolant tempera-
ture sensor power supply voltage do not
meet specs.

P1561 (*)
VOLTAGES
SENSOR 2
The TPS sensor and temperature sen-
sor power supply voltage does not meet
specs. Too high voltages may be rec-
ognised.
Forced idle On
If one or more errors are detected, or differences are detected between the values shown in the pa-
rameters, check the circuit and sensor using the troubleshooting procedure.
1. Install the interface wiring ECU.
Specific tooling
020481Y Control unit interface wiring
Omit the connection to the ECU. Disconnect the connector of sensor TPS and of the coolant temper-
ature sensor.
