P0029 Code for 1994 Z28 with 4L60E
I have a 1994 Z28 with an automatic transmission. I get an intermittent service light and a P0029 code is referenced. When this happens the car seems shift harshly. 1994 should be OBD - I, right? I thought P0029 is an OBD-II code? -- P0029 Exhaust Valve Control Solenoid Circuit Range/Performance (Bank 2)
Does this refer to an engine problem or transmission? If it's an engine problem why would this affect the transmission shifting? I could see a TPS sensor doing that, but what does this refer to, exactly. Wouldn't it be related to a shift solenoid problem since it's a 4L60E transmission?
Googling only brings up posts that list the codes--nothing specific on how to resolve the issue. If this is a valid code, what can I do to fix the problem? Is there a specific solenoid I need to look at?
Thanks in advance for the help!
