| Complaint: | Customer complaint about the following symptoms: a.) Engine stalls during driving b.) Engine does not start c.) Engine starts but will not respond to throttle pedal |
|---|---|
| Cause: | At high (ambient) temperatures gel within the ECU plug will pour into the pin connector and therefore avoiding electrical contact which affects the rail pressure signal resulting into P0093. |
| Production: | Implementation of new engine wiring harness in production as of engineno.: - Corsa-C, Combo: Z17DTH1357491 as of 11.7.2005 - Meriva (100 A alternator): Z17DTH1359428 as of 13.7.2005 - Meriva (110 A alternator): Z17DTH1340705 as of 1.7.2005 |
Remedy:
In case of customer complaint proceed as follows: Before any repair, conduct fuel leak test with TECH 2. TECH 2 has a fuel leak test function, that load 180Mpa to the fuel line (At the idle condition, there is only 35Mpa). Check visually for any fuel leak! If leak found, repair according to TIS 2000 instruction.
1) Fuel pressure value read out at engine stop condition by TECH 2. If it is more than 1Mpa, exchange the engine wiring harness.
2) If the vehicle had no response for throttle right after engine started, replace engine wiring harness.
3) If the engine stall by TC P0093 occurred at high load condition, replace the rail. (The pressure limiter on the rail open at over 211Mpa and TEC 2 can make 180Mpa at the fuel line. If the pressure limiter open between those pressures, ECU may set TC P0093 and stop the engine.
Note: If 2) or 3) is not clearly to identify contact ETAC for guided root cause analysis.
Note: With the new wiring harness the electrical plug for the swirl actuator was deleted. This feedback signal was never used by the ECU therefore it was decided to delete mentioned plug from the wiring harness. Nevertheless the vacuum line must be connected to the vacuum box.
