I'm experiencing some hesitation and jerk sometimes when accelerating.

I'd appreciate if you guys can help me diagnose the problem and find a solution for these codes.
There are my new codes I picked up at autozone....

P0116 - Engine coolant temp circuit range/performance
P0102 - Mass or volume air flow sensor circuit low input
P1426 - Tank ventilation valve open circuit
P0411 - Secondary Air injection system incorrect flow
P1476 - EVAP control system LDP malfunction/insufficient vacuum
P0432 - Catalyst efficiency low-bank 2

Thank you

 

anyone?

 

Id start by either replacing both the coolant temp sensor and the MAF, or cleaning the MAF and cleaning the connector of the coolant sensor (cleaning them might work, it does for some, me included but no gurantees). I would guess that should smooth out driving.. The other codes are emissions stuff mainly, which i dont know all that much about..

Some of those codes might be remnants and might not come back.. Id clear them and recheck them to see which ones come back.

 

Allright I think I'm on the right track then....the connector for my coolant sensor is blue, so my actual sensor would be blue or black(new style is green) ?

Thank you very much!

 

You'll need the blue sensor. I agree that clearing the ECU to see what codes are currently active is the best first step. Try that, see what returns, post those codes up, and we can go from there.

 

Ok just purchased a coolant sensor from ecstuning. After I replace it I'll reply here with the codes..

Help much appreciated
