Default Error codes

Can someone tell me what the following error codes mean when a diagnostic is run? Thanks.

13, 45, 68, 71, 95

You have three different types of codes here.
Two engine fault codes( will cause SES light to light)
Code 13- O2 sensor open/not ready
Code 45- O2 sensor reads rich mixture.

Engine information code( these codes won't set the SES light, Their purpose is to assist in in the diag and repair of fault codes)
code 71- cooling system temp high

The other two are Transmission codes.
Code 68- Line pressure actuator circuit is grounded or open
Code 95- intermittant fault on line pressure circuit.

Without any symptoms to go by, looks like the O2 sensor is on it's way out (code 13)
The code 45 could be related to the O2 sensor or possibly a misreading PCM coolant sensor.
The code 71 doesn't usually set for a misreading coolant sensor, usually it IS due to a high temp reading ( the coolant sensors tend to read cooler than the actual temp when they fail). So for the code 71 I'd check for an inop cooling fan or another cause of an overheat condition.

As for the two trans codes. Seeing as you have the code 95 it is probably not the line pressure fuse, though check it anyway( underhood fuse box). Possibly either a bad line pressure actuator or a partially broken wire, The wires to the trans run under the A/c hose. This is the place they break most often. Split the harness at that point and check the wires.

Enough information?

Thanks for the info. That is great. The codes were in reference to my other post regarding my transmission/valve body problem. I forgot to ask what the codes meant so I used a separate post to hopefully get the answer.

Thanks again. That is great.
