Corrective action:
Check for pin back out.
Check for open circuit.
Replace the rail pressure sensor along with the rail.
P0087: Rail pressure does not build within the speculated time.
P0088:
Rail pressure exceeds the Calibrated pressure limit in absence of fault in
pressure measurement
P1253: Rail pressure control error (pressure error too high) – Negative
P1254: Rail pressure control error (pressure error too high) – Positive
P1256: Rail pressure control error (IMV current trim drift) – Low fuel low fault
P1257: Rail pressure control error (IMV current trim drift) – Low fuel high fault
P1258: Rail pressure control error (IMV current trim drift) – High fuel low fault
P1259: Rail pressure control error (IMV current trim drift) – High fuel high fault
Corrective action:
1.
IMV fault present
Refer fault tree P 0251, 0253 & 0255.
2.
HP sensor fault present
Refer fault tree P 0192, 0193, 0194 &
190.
3.
LP Circuit Problem
Low pressure checks:
A. Fuel level in diesel tank (check physically)
Fill if it is empty
B. Air in the circuit - Remove air entrapment (Do not loosen HP pipes
C. Filter connection and LP fuel lines - Connect properly.
D. Strainer in Fuel tank -
- Strainer checks:
i. Remove & replace strainer if choked,
Tighten strainer & banjo joint properly
ii. Change if found defective
iii. Connect properly
4. HP Circuit Problem - 4. Perform High Pressure Diagonistics
