P1133: Pto Accelerator Sensor (Hi); Dtc: P1133 - Hino Motors HINO 155 series Workshop Manual

2–736

DTC: P1133

P1133: PTO accelerator sensor (Hi)

INFORMATION
1. Technical description
• The operational accelerator sensor measures accelerator opening if PTO (power take off) is used. (This applies
only to PTO-equipped vehicles.)
<Description of malfunction>
• The operational accelerator sensor cannot correctly sense.
• +B short-circuit is likely to have occurred.
2. DTC set condition
(1) DTC detection condition
• Key is ON and starter is OFF.
• Battery voltage is in the range of 10 V to 16 V.
The conditions described above remain for 5 seconds or longer.
(2) Judgement criteria
• Sensor voltage remains at 4.82 V or higher for 3 seconds or longer.
3. Reset condition
• After normal operation is restored and accelerator opening is fully closed.
4. Indication, warning or system control regulation when the DTC is set.
• MIL: OFF
• SVS light: OFF
• Body mounting control is not available.
5. Symptoms on the vehicle when the DTC is set
<Symptoms on the vehicle due to backup control (fail safe function)>
• –
<Symptoms on the vehicle due to malfunction>
• Body mounting control is not working.
6. Pre-inspection work
• Check that the battery voltage is in the normal range.
7. After-inspection work
• Clear all past DTCs.
• Check that no DTC is stored after test drive.
8. Estimated failure factors
• Faulty harness (+B short-circuit)
• Malfunction of PTO accelerator sensor (operational accelerator sensor)
• Failure in engine ECU sensor power supply or internal circuit
