The Service Ride Control light just came on.It's a code 64.Has anyony had this problem?I just put in a new Throttle pos.sensor and the code returned.

bogus

uh, the TPS has anything to do with SRC?

I would think it's time to debug the SRC. Do you have a manual?

ECM DTC(Diagnostic Trouble Code) 64, "right o2 sensor lean", is constant or intermittent?
GM Service Manual , book 2 of 2, page 6e3-A-95,
Diagnostic Aids; could be any of the following.
o2 wire,
MAP sensor,
Lean injector(s),
Fuel contamation,
Fuel pressure,
Exhaust leaks,
AIR system,
If all the above are OK, the o2 sensor may be at fault.

ABS/ASR DTC 64, "throttle postion signal fault"
GMSM, book 1 of 2, page 5e1-86,
Code 64 will set if the EBCM (Electrontic Brake Control Module) is not receiving reference voltage or a TPS signal from the Throttle Position Sensor Module.

The first CODE 64 given by C4crazy is the correct code if you got it from watching the "check engine light" flashes or read it from the dashboard speedo readout by groundinf A and G on the ALDL, unless you fot it from section 9.1 ( EBCM ) of the diognosis sequence.
Consentrate on the steps in the order he set out sort this out ........... and........... report often and ask alot of questions.

Code 64 from 9.1 says TPS-I should have stated that earlier.The TPS was replaced and even after clearing the code it returns.This is the only code I get.
