  • Here, hold this while I try to go over that.
OK, I've got a 95 1500 with a 5.3L engine. 88K miles. Occasionally, the check engine light comes on. Sometimes
when I start it and sometimes when it's been running. it doesn't stay on. Before a go to the local stealer, can anyone tell me the different reasons the light may come on? It got a new cat installed at about 65K miles (still
under the warranty). Any help would be appreciated. Thanks.
Who needs more than 63HP??

I am a master tech at a dealer here in california.  There is over 100 reasons why the check engine light comes on. You need to have the code checked out, and then determine what to do to fix it. Or you will be wasting time and money and your sanity.

Just for kicks though, I am going to guess the Oxygen sensor, upper or lower


Trust me, have the code checked, you can buy a code reader from Kragens, (or whatever parts house you have) or take it to any shop with a scan tool, read the code, and if you have any mechanical ability, fix it.

Thanks guys for not flaming me on the 5.3 typo. Someone on my local board was quick to point out that a 318 is a 5.2 not a 5.3.

Ok, found a link ( http://www.dodgeram.org/tech/gas/Trouble/pcm_fault_code.htm ). Appears this 95 was delivered before the OBD II universal codes mandated in 1996. Lucky for me, the link pointed out how to read your own codes by turning the ignition on, off, on, off, on and counting the blinks on the check engine light. Got 2 codes. Now, what do they mean?

31: EVAP Solenoid Circuit - Short or open in the EVAP solenoid circuit. Check for loose, broken, or shorted wire in the charcoal canister purge solenoid wiring and connectors.

37: Torque converter clutch solenoid CKT or Trans temp sensor too high or low - Open or short in CKT wiring or connectors. Voltage out of range at transmission temperature sensor input. NOTE from the 1995 TRUCK (Ram) manuals: the trailer towing package includes a transmission coolant temp sensor while the standard package doesn't. The fault code detection system is probably the same for both models. This could cause the low (no) voltage indication....no sensor to send any voltage.

How would I go about checking these 2 issues? How do I know if this truck has the trailer towing package? Are either of these issues a huge problem that need attention immediately? Nor-Call Zukini, I know you work for a dealer and I don't want to put you on the spot but if there is any info you could pass my way, I would greatly appreciate it. I just don't have the time or money for the dealer to work on this. The shops here are closed on weekends.

   The tranny code is probably fictitious. If the truck doesn't have a locking converter it will set that code but that code won't set a light.  They use the same computer for all trans and the ones without a locking converter will have that code.

Sorry I havnt kept up here, been busy.

The canister is on the frame rail about at the end of the transmission. It will be one or two plastic rectangular boxes. There is a purge solinoind under the hood, above the left valve cover mounted on a stud of the firewall. It will have two plastic line hoses and a wire connecter. I will post up the diag flow sheet for both the problems.

The trans sounds like a range sensor problem................stand by :)

Notes
 
No. 7631

June, 1998

To: All Dodge Truck Dealers

Subject:
Emissions Recalls # 7631 and # 7632 -- Vapor Canister and Purge Solenoid

Models:
1994 Through 1996 Model Year Dodge Ram (BR) Trucks Equipped With a Gasoline Engine and:

^ Recall # 7631 -- Currently Located Out of California
^ Recall # 7632 -- Currently Located In California
 

The evaporative vapor canister on about 635,000 of the above listed vehicles, may allow charcoal to migrate from the canister to the purge solenoid and into the engine. The missing canister charcoal may allow fuel vapors to escape into the atmosphere, in violation of U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) emission regulations. In addition, the migrating charcoal may plug the purge solenoid, which may cause driveability complaints and illumination of the Malfunction Indicator Light (MIL). To correct this condition, the vapor canister and purge solenoid must be replaced.

IMPORTANT :This recall (# 7632) is subject to the State of California Registration Renewal/Emissions Recall Enforcement Program. Involved vehicles must have the recall service completed before registration renewal.

The servicing dealer must provide a Vehicle Emission Recall Proof of Correction Form (Form No. 81-016-1053) to each California vehicle owner upon completion of the recall # 7632 service, for use as proof in renewal of the vehicle registration.

Dealer Notification & Vehicle List

All dealers will receive a copy of this dealer recall notification letter by first class mail. Each dealer to whom involved vehicles were invoiced (or the current dealer at the same street address) will receive a list of their involved vehicles. The Vehicle List is arranged in Vehicle Identification Number (VIN) sequence. Owners known to Chrysler are also listed. The lists are for dealer reference in arranging for service of involved vehicles.

Dial System Functions 53 and VIP

All involved vehicles will be entered to DIAL System Functions 53 and VIP at the time of recall implementation for dealer inquiry as needed.

Function 53 provides involved dealers with an updated VIN list of incomplete vehicles. The customer name, address and phone number is listed if known. Parts information is also provided. Completed vehicles are removed from Function 53 within several days of repair claim submission. To use this system, type "53" at the "ENTER FUNCTION" prompt, then type "ORD7631"(vehicles out of California) or "0RD7632" (vehicles in California).

Recall Completion Label Requirement

There is a California Air Resources Board requirement to affix a label to the vehicle to certify that the emissions recall (# 7632) was completed. Dealers are requested to order the required Authorized Modifications Label, PN 04275086, as necessary to support scheduled repairs. Refer to the Service Procedure of this letter for application instructions.

Parts

IMPORTANT: A quantity of parts will be distributed initially and billed to all involved dealers. This quantity will cover a portion of the total vehicles involved. Additional parts may be ordered as needed to support customer demand.

Each involved dealer, to whom vehicles in the recall were invoiced (or the current dealer at the same street address), will receive enough Vapor Canister Packages to service about 30% of those vehicles.

Dealers should determine which parts package is required for each vehicle at the time appointments are scheduled to assure that the correct parts package is available when the customer arrives.

Model Year          Part Number

1996                CLT27631
1994 and 1995       CLUN7632

Each parts package contains the following components:

Quantity       Description

   1           Vapor Canister
   1           Purge Solenoid

Owner Notification and Service Scheduling

All involved vehicle owners known to Chrysler are being notified of the service requirement by first class mail. They are requested to schedule appointments for this service with their dealers. A copy of the owner notification letter is included.

Enclosed with each owner notification is an Owner Notification Form. The involved vehicle and recall are identified on the form for owner or dealer reference as needed.

Completion Reporting and Reimbursement

Claims for vehicles which have been serviced must be submitted on the DIAL System. Claims submitted will be used by Chrysler to record recall service completions and provide dealer payments.

Use the following labor operation number and time allowance:

Replace vapor canister and purge solenoid

Labor Operation Number        Time

25763182                      0.4 hours

OK for the trans problem. You will need to drop the trans pan and replace the TCC and 3-4 shift solinoid. It may come with the wiring harness that has the trans temp sensor built into it. If it doesnt, get the harness also.  Fill the trans back to specs. (get a new filter while your at it and a case of trans fluid, make sure you get ATF+4) and you should be good. Not a hard job, just alittle messy.
