Chrysler PT Cruiser Computer CodesGetting the codesAll Chrysler vehicles with fuel injection have had some form of "error checking." In many older vehicles, a person could easily turn the key back and forth a few times to get a two-digit code. With the PT Cruiser, a longer code seems to be used. In addition, as with all vehicles sold in the United States, the system is OBDC3 compatible, so that a standard diagnostic device can be plugged into a standard jack to get computer codes.
When some problems are found, the computer lights up the "engine light;" others are ignored until a mechanic asks for them. The "engine light" stays on when a serious emissions or engine problem is found, until the code is erased.
Chrysler vehicles have a "limp in" mode which reverts to a pre-programmed "guessing map" for timing, fuel delivery, etc. when a critical sensor fails. Those who have been in other cars when their oxygen sensor failed can feel grateful for this feature, though it can be confusing - for example, in some (maybe all) models, the automatic transmission is limited to second gear! The engine light also turns itself on for two seconds every time the car is started so you will know the bulb still works.
The "engine light" may shut itself off if there are no problems for three consecutive trips, or three consecutives engine misfire or fuel system tests with no problems.
To get the codes, move the key from Run to Off to Run to Off to Run within five seconds. It does not always work the first time. (Run is JUST before Start). The code will show up in the odometer - thank your lucky stars for this, since the codes used to get blinked on the engine light. Alan Borgolotto noted that “if you do it too quickly it doesnt work (got to wait to see the odometer light up” and that if you have no codes, the odometer will say “done.”
Another method which may in most cars just test the instrument panel is to put the key into the ignition, push down the odometer reset button, then turn the key to RUN with your finger on the button - and then release the button. The odometer will go through 1111111 through 999999, then display the car's serial number and some other, irrelevant information, then show the error codes starting with P. Note that this method may not work. It's easier but not necessarily better.
You can also get the codes using an OBDC III scan tool. That's the best way to do it, but not everyone wants to spend the cash on these tools.
No matter which method you use, some codes will not appear - codes specific to Chrysler such as individual transmission malfunction codes. Dealers and some specialty shops can get these using a terribly expensive scan tool.

176 Flex fuel sensor can't be seen
178 Flex fuel sensor problem
179 Flex fuel sensor problem
182 Compressed natural gas temperature sensor problem
183 Compressed natural gas temperature sensor problem

302 Misfire detected in cylinder #2.
303 Misfire detected in cylinder #3.
304 Misfire detected in cylinder #4.
320 Crankshaft position sensor reference signal cannot be found while the engine is cranking.
325 Knock sensor (#1) signal is wrong.
330 Knock sensor (#2) signal is wrong.
340 No camshaft signal being received by the computer
350 A coil is drawing too much current.
351 Coil #1 is not reaching peak current at the right time
352 Coil #2 is not reaching peak current at the right time
353 Coil #3 is not reaching peak current at the right time
354 Coil #4 is not reaching peak current at the right time
401 A required change in air/fuel mixture was not detected during diagnostic test.
403 An problem was detected in the EGR solenoid control circuit.
404 The EGR sensor's reported position makes no sense
405 EGR position sensor voltage wrong.
406 EGR position sensor voltage wrong.
412 The secondary air solenoid control circuit seems bad (this is used for the aspirator).
420 The catalyst seems inefficient (#1).

We have a 2007 PT Cruiser ande are having the same problem. Just got back from the dealer and they could not find the problem. Any luck yet with diagnosing the problem.

I just took it to an mechanic that specializes in electrical issues and he's trying to narrow it down. He's thinking it has to be the wiring under the panel in of the steering column, but he's not for sure for sure. Now one of my friends knows of a Cruiser that had the same or extremely similar problem, I told her to ask the dealership selling the car what they did to solve it. Also by any chance, on your PT have you had any after market work done to it that would interfere with the wiring or involve any of the wiring.
Oh quick question for you; I keep hearing that there are two fuse boxes in my car but can't find the other one for anything. I know of the one under the hood, but where's the second one? Would you happen to know?
#235 of 336 Battery drains
Jul 17, 2009 (5:06 pm)
Our '03' Cruiser battery dies. We experienced this a month ago, and I recharged batt. Then it happened again a week later, so I decided that the original batt must be giving up the ghost. Got new one at WalMart, and no problems for a month, then yesterday morning - dead batt -. Put the charger on for an hour, then started car and ran for about 5 minutes. After shutting off engine, I removed neg (-) terminal and looked for power drain by using milliAmp reading from neg (-) post and the now disconnected neg (-) cable. Initially I was in the 70 milliamp draw, but that dropped to about 9 milliAmp after about 3 or 4 minutes (I assume computers shutting off for the delay). So I went to bed happy that there was no batt drain. Today after no use all day, I went out to it this afternoon and it is totally dead again. To note, our weather has been in the 100's for a few days now. We also have noticed for a few weeks that the AIRBAG light stays on during engine running time. we have noticed a couple of times the FOG lamp is lit, but that has only been a couple of times in the last 6 months.

pull the fog light fuse (or replace the control cluster unit on the steering column with the turning signal and light controls).
just LAST WEEK i finally got my problems fixed
after i replaced the battery, ignition module, two starters and the computer.
oh, and several tows home from Philly.
the battery cables were bad - specifically the positive cable. it looked good and i had plenty of power for lights - but not enough to the starter.
so far so good - AND it was under $100 for the cables - almost $200 for the diagnostics and the labor - BUT it's fixed - knock on wood!!!

Did you ever get this problem fixed? I have a 2007 PT Cruiser that is doing the same thing and they are going to replace the hazard switch which is apparently the hottest of all the knobs (but they all get hot). I don't think switching one switch is the answer. I can smell something burning, but apparently the technicians can't. I am also afraid it will catch fire.

I have a guy that's going to look at my wiring for my tail lights and interior dash. Did anybody check your wires to make sure nothings rubbing and it shouldn't be or there aren't any lose wires somewhere? You really shouldn't even be driving that car if it smells like somethings burning.I really hope you get that checked out and fixed soon.
#239 of 336 Dashboard dead
Aug 20, 2009 (1:26 pm)
2005 PT convertible turbo. The dash suddenly stopped working. No odometer, fuel gauge, speedometer, etc. Radio works interior lights do not. Car starts and runs fine. Anyone with similar problems? Fuses appear to be fine checked dash fuses with continuity tester.

Thanks for your reply. The dealer checked everything, at first couldn't find anything wrong. Then he burned his finger on the emergency flasher, which he replaced. It hasn't got sizzling hot since, but warm, but only when the lights are on, which isn't often. Haven't smelled anything burning since.
#241 of 336 2003 PT cruiser wont start.
Aug 24, 2009 (4:56 pm)
I have a used 2003 pt cruiser. About a week ago the electrical light came on while I was driving. (The one that looks like a battery.) After a while the vehicle started to drive funny...Like it didnt have much power. I took it home and parked it. It was starting fine...until one evening (couple days later) when I desided I would drive it. It wouldnt start. The dash would light up but the engine didnt turn over instead I heard clicks. Soooo...We got a new battery. It started but then...it cut off. So now we are thinking it may be the altenator??
