Any experience with these Check Eng codes?
PCM P0171H Fuel Trim System Lean
TCS C1234H, C1235H Wheel speed Sensor Circuit
TCS C1248H DRP Disabled
Got light last night, car is a 2004 Z16-Z06, has Halltech intake and Carolina Auto Masters mail in tune. Going to have Jeff do a dyno tune when I can get down to Durham but any experience with these codes from you guys would be helpful.
Thanks,

I do have some exp with the c1234 & c1235,c1248 These Tcs codes are all current c1234 code is a wss code i think its the LR wheel Speed sensor circuit shorted or open ,what u can do to elimanate the connectors is to swap it out from the otherside & see if it went away ,u should get 1235 ,but since u allready Have a 1235 i would look into A Bad Ground ,Also U may wanna hook up an Ohlms meter & Check the Resistance Between terminal A & Ground if u go thru the Process of checking your wiring & connectors & All the values come up to within range specified u may end up having a Bad etbcm ,I just Had to repace my Module over the c1233 code ,ended up not having any value on Terminal 14 on the Module itself ,The c1233 is The Front pass wss ,The 0171 fuel Trim code is a history code ,u may wanna delete it & see if it comes back ///c1284 code ,This code is thrown if it does not see an expected change in output of the lateral accelerometer soon after intialization ,lateral accelerometer Performs a self test @intlazton ,the sensor output will be offset by a fixed amount for a Short Period of time when the Ebcm powers up ,the test will run when the ign is on & all 4 speeds are km/m & the steering angle is within 90 degrees of straight ahead,I have no exp with the 1284 code just giving u a Heads up on What the manual says about this code [QUOTE=YorkL8apex;1562214046]PCM P0171H Fuel Trim System Lean
