```My response only provided the replacement definition for p3. At a minimum, the OP's definition of f must also be used.

f[\[Theta]_, \[Phi]_] = Sin[\[Theta] + \[Phi]];

p3 = SphericalPlot3D[1, {\[Phi], 0, Pi}, {\[Theta], 0, 2 Pi},
ColorFunctionScaling -> False,
ColorFunction -> Function[{x, y, z, \[Theta], \[Phi], r},
ColorData["TemperatureMap"]
[Rescale[f[\[Phi], \[Theta]], {-1, 1}]]],
Mesh -> 9,
MeshFunctions -> {Function[{x, y, z, \[Theta], \[Phi], r},
f[\[Phi], \[Theta]]]},
BoundaryStyle -> Transparent]

Hi Bob;

what version of Mathematica did you use? on 8.0.1,
windows 7, I get an error message.

MeshFunctions::invmeshf: MeshFunctions->{At Line = 1, the input
was:,p3=SphericalPlot3D[1,{\[Phi],0,Pi},{\[Theta],0,2Pi},ColorFunctionScaling->False,
ColorFunction->Function[{x,y,z,\[Theta],\[Phi],r},
ColorData[TemperatureMap][Rescale[f[\[Phi],\[Theta]],{-1,1}]]],
Mesh->9,MeshFunctions->{Function[{x,y,z,\[Theta],\[Phi],r},f[\[Phi],
\[Theta]]]}],f[#5,#4]&} must be a pure function or a list of pure functions. >>

here is a screen shot also fyi
