CONDITION SUMMARY:

Situation: Inadequate A/C performance may be exhibited. Upon inspection, low pressure is recorded on the high pressure system, high pressure recorded on the low pressure system, and the compressor clutch (where applicable) is working properly.

Cause: This may be caused by the A/C compressor Direct Pressure Sensing (DPS) valve being worn.

Action: Should a customer express this concern, follow the Service Instruction outlined below.

SERVICE INSTRUCTION:

NOTE: Prior to carrying out the service instruction, carry out the Climate Control System – General Information – Diagnosis and Testing (see TOPIx Workshop Manual, section 412-00). 

NOTE: The Direct Pressure Sensing (DPS) valve may also be referred to the Electronic Control Valve.

1. Remove the A/C compressor:

• F-TYPE (X152): see TOPIX Workshop Manual, section 412-01
• XF (X250), XJ (X351), XK (X150): see TOPIx Workshop Manual, section 412-03

Replace the A/C compressor Direct Pressure Sensing (DPS) valve replacement procedure. 

2. NOTE: Make sure foreign materials do not enter the Direct Pressure Sensing (DPS) valve hole on the cylinder head when the DPS valve is removed.

Using compressed air or similar, remove all foreign materials from around the DPS valve/cylinder head.

 

3. CAUTION: Make sure not to damage the circlip housing in the cylinder head.

Place the A/C compressor on a clean flat work surface.

Using a suitable tool, remove and discard the circlip that retains the DPS valve in the compressor cylinder head.

4. CAUTION: Make sure not to damage the housing in the cylinder head.

Using suitable tools, release the DPS valve.

 

5. NOTE: Take care to remove the DPS valve in a vertical direction to avoid damage to the inside wall of the cylinder head.

Remove by hand the DPS valve from the A/C compressor cylinder head; discard the DPS valve.

 

6. Inspect the inside wall of the cylinder head for Scratches, Scoring, or foreign material.

 

7. Apply compressor oil (Polyalkylene Glycol [GPA] SPA2 Oil) to the O-rings of the new DPS valve.

 

8. Install the DPS valve:

• Apply a downward pressure by hand.
  • If required, use a suitable tool to press fully into position to allow installation of the new circlip.

 

9. Using a suitable tool, install the new circlip supplied in the kit.

 

10. Install the A/C compressor:

• F-TYPE (X152): see TOPIX Workshop Manual, section 412-01
• XF (X250), XJ (X351), XK (X150): see TOPIx Workshop Manual, section 412-03
