Error Code set condition
1st step
• Rail pressure is more than 185MPa for 5 seconds
or more.
• Common rail pressure sensor voltage is 3.9 V or
more.
2nd step
• 1st stage is completed, and rail pressure is more
than 190MPa for 5 seconds or more.
• Common rail pressure sensor voltage is 4.0 V or
more.
Action taken when Error Code is set
• "ELEC. PROBLEM" is displayed.
Back-up mode
• L mode fixed.
• Limited injection amount 3 (multi-injection stopped)

Recovery from failure
• Recovery pattern 1.
Refer to “List of diagnostic trouble code” and “About
recovery from failure” error.
The conditions to clear the Error Code
• The error code is cleared from the current trouble
when the condition is either repaired or
disappeared.
Refer to "About recovery from failure".
Diagnostic aid
If the intermittent trouble is suspected, followings may
be the cause.
• Improper connection of harness connector
• Defective harness routing
• Worn harness cladding
• Wire disconnection inside harness cladding
Following inspections are necessary to detect these
causes.
• Improper connection of harness connector and
ECM connector
– Poor connection of terminal from connector
– Unmatched terminals are fitted.
– Damage of connector lock
– Poor contact between terminal and wire
• Damaged harness
– Visually check the harness for damage.
– Check the relevant items while moving the
connector and the harness which are related to
the sensor.

2
1. Start the engine.
2. Check the Error Code.
3. Are the fuel-related parts only just
replaced?
Air bleeding may not be performed
sufficiently after replacing fuel-related
parts. Bleed air again. Check the Error
Code after bleeding air.
Is any of the 0088, 0192, 0193, or 1635
detected?
