P0218 - Transmission Over Temperature Condition
P0714 - Transmission Fluid Temperature Sensor Circuit Intermittent

Both of these codes appear to be related to a single cause. The second one is caused by something changing intermittently. A loose or corroded terminal in a connector is a good suspect. Corrosion between two adjacent connector terminals could lower resistance in the circuit which would show up as an apparent higher temperature. First check the wiring and connector terminals for that sensor. Next, you'll need a scanner to view live data. Watch the reading for that sensor as you wiggle the wiring harness. If you see a sudden change, you're in the right area.

Temperature sensors don't fail very often but don't overlook that as a possible cause too.

I checked the connector it looked good. However what I noticed today is that the radiator fan is all the time on even when the hood is on and the car is in the shade. Also I checked the temperature of the transmission it was around 160

Next you'll need a scanner to see what the temperature sensors are reading and to see if the radiator fan relay is being commanded on by the Engine Computer.

Ok the pt cruiser is driving me nuts. When I connected the code reader to the DLC suddenly when I turned the ignition to on two codes came out p1604 PCM INTERNAL DUAL-PORT RAM READ/WRITE INTEGRITY FAILURE and U0101 LOST COMMUNICATION WITH TCM.

I subscribe to alldatadiy but I could not find pcm diagram to check power and ground

Continued

sorry the code was P1603-PCM INTERNAL DUAL-PORT RAM COMMUNICATION FAILURE and on alldata they said causes are

POSSIBLE CAUSES
PCM fused ignition switch circuit
PCM internal

Diagnostic Test

1. PCM IGNITION CIRCUITS
Turn the ignition off.
Disconnect the PCM harness connectors.
Ignition on, engine not running.

CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install Miller Special Tool #8815 to perform diagnosis.

With a 12-volt test light connected to ground and with special tool #8815 installed, probe the (F202) and (F924) Fused Ignition Switch circuits.
Perform the above check with the Ignition key in the off lock position, Ignition on, engine not running position, and during cranking.
Wiggle the related wire harness while probing the special tool with the test light to try to interrupt the circuit.

Q: Does the test light illuminate brightly?

YES: Go To 2
NO: Repair the open or excessive resistance in the (F202) and (F924) Fused Ignition Switch (Off, Run, Start) circuits. Inspect the related fuse, if the fuse is open check the circuits for a short to ground. Perform the POWERTRAIN VERIFICATION TEST. See: Verification Tests Powertrain Verification Test

and I dont know where is those circuits (F202) and (F924)

Erase the codes, then see if they come back. I'm betting they won't. We see these once in a while; they set for who knows why but most of the time there isn't a problem related to them. If they do come back, it's almost always due to a blown fuse. It's pretty common to blow a couple of fuses from just reconnecting the battery. Current surges from computer memory circuits charging up do that.

This is the second time I see those codes the first time was like 2 months ago.I checked the fuses some of them they have like burning marks only on the 'legs' the two pins that goes inside the TIPM. But the fuse is good. Do I should replace them?

Shine the fuse terminals up with some fine sandpaper. Also be sure the terminals in the fuse box have proper tension and aren't spread.
