Checking short-circuit

WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

The fuel tank pressure sensor power cable is connected inside the engine control module (ECM) to the accelerometer and air conditioning (A/C) pressure sensor power cables.
If anything happens to any of these cables all three will be affected.

Check cables between:
- Tank pressure sensor terminal 3 and control module #B15.
- Accelerometer terminal 1 and control module #B1.
- Air conditioning (A/C) pressure sensor terminal 3 and control module #B29 for a short-circuit to ground. Short-circuit to ground, permanent faults .
Remedy as necessary.
