How Can You Fix The Chevrolet P1175 Code?

NOTE: All of these tests are much more effective if the throttle body is covered/sealed.

• For an intake leak the smoke can be introduce into the brake booster hose or the oil dipstick tube.
• Soapy water can be sprayed near the gasket and seams and all vacuum nipples.
• For an exhaust leak the hose into the tailpipe, with smoke or air, sealed with shop towels
  proves to be effective. Then soapy water would be sprayed around seal, seems and bosses. Ultrasonic leak detector may also find leaks in this way.

These methods are very good for finding small leaks around the O2 sensor embossments and slight cracks in an intake plenum or gasket.
