LPG PUMP OPERATION CHECK

Check 1043AA

2.0 16V · GPL

The operation test involves carrying out an overall power uptake test for the following loads:+

• LPG pump;
• Solenoid on LPG cylinder

Proceed as follows:

• With all loads deactivated, measure battery voltage and ensure that no-load voltage is at least 12.8 V. Otherwise charge the battery.
• Turn the ignition key to the OFF position;
• Fit an ammeter probe to the battery negative lead.
• Disconnect the LPG pump current sensor from the connector
• Connect the connector terminal connected to the current sensor V to the battery +12 V via a bridge with a 15 A fuse interposed.

Check that overall load uptake is:

• approximately 4 A with the LPG tank empty;
• approximately 6.5 A with the tank full of LPG.

Switching to LPG is inhibited if current uptake by the LPG pump does not exceed a threshold of4 A, corresponding to tank condition when not empty.
