does anyone know what it is exactly?id try and look it up myself but im getting poor or no connection..thanks for any help or suggestions,i drove from gulfport Ms. to El paso Tx today and im worried if im doing futher damage

 

P0351 Ignition Coil "A" Primary/Secondary Circuit Malfunction

I'd reset your ECU and see if it comes back.

 

Just a quick google search shows that code to mean there is a problem with the number one cylinder ignition coil.

If it runs okay and does not miss, I would pull the negative battery cable for a couple minutes to reset the computer and keep driving it. I did that on a Jeep with the same type of trouble code and it never did come back.

If it is missing, then you can damage the catalytic converters and possibly the engine itself. If you are noticing any significant lack of power, stumbling, shaking, etc, then it needs to be dealt with asap.

 

There is also this... not sure what it means.

"MIL "ON" DTC P0351, P0352, P0353, P0354, P0355, P0356 (T-SB-0047-10)

Some 2008 – 2010 model year vehicles equipped with 2GR-FE engines may exhibit a MIL “ON” condition with Diagnostic Trouble Code (DTC) P0351, P0352, P0353, P0354, P0355, or P0356 (Ignition Coil Primary/Secondary Circuit) stored in the Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM)."

Says there is a TSB about it

 

Thanks Tacoma family..I reset the light and it did come back on within 40 miles..I'm going to switch out the ignition coil when we stop for the night..I'll look at all of the coils but for quick reference, primary coil on 6cyl 07 camry is front passenger side,right?

 

I believe that's correct.

But you should read that TSB above. If it's still running good, might just be a ghost in the computer.
