#76 of 95 intermittent 'service engine soon'
Nov 10, 2009 (12:39 pm)
I have a '98 S10 with a manual trans & a 4cylinder (2.2?) engine. Ever since I've owned it, the service engine light has gone on for a long time, then suddenly off for a short time, then on again...a mechanic told me it was a code 0404, indicating a need to replace the linear EGR valve, which I did myself. No change, however, except that the light seems to stay off longer than before. The truck unexpectedly dies sometimes after I've driven it all day. Usually starts up right away, but then dies again (all dash lights go off except for the battery light).If it sits for a while,it seems fine again. Could the service light and the dying be related? Brand new battery; checked and cleaned terminals and cables...I'm stumped.
Any input would be greatly appreciated.
#77 of 95 01 Chevy S10 SES alarm after Pressure wash
Dec 09, 2009 (10:59 am)
I have a 01 chevy s 10; I pressure washed the engine to get rid of a rat and about the same time switched to a locking gas cap. less than 20 miles later the SES light turned on. I've had it checked and reset 3 or 4 times resulting in misc different codes but the primary one has been a slow leak in the evap system. Recommendations of hte problems have been the pump, the hoses, the gas cap, the carbon cannister, or the pressure valve. So far, I have pulled the cannister and check for fuel or blockage; its ok; the solenoid valve was pulled and cleaned, it had road dirt on it and around it, it can be dismantled, and the valve was cleaned and tested to about 5 psi even though the system only works at 1 psi. A third, brand new, gas cap was installed with the last reset of the obdII, this seemed to work for about 3 fill ups and about 600 miles, now the SES light is back on! I'm thinking its related to one of those plastic hose fittings going into what I think is the manifold near the top of the engine. Anybody got any suggestions? V6, 2001, about 85K miles, owned since new, maintained by me above average mechanical skills, degreed electrical engineer with general purpose test equipment, but no speciallized car test equipment.

I have an S10 with 97,000 miles, and P0141 code is showing. What's the typical fix for this? Will replacing the downstream O2 sensor fix it? Also a P0303 (cyl 3 misfire) showed up in code history log. Is that spark plug/ wires?

The 95 S-10 is a crossover model, however, it is NOT OBDII compliant. It is quite confusing having the 16-pin DLC instead of the 10-pin ALDL. An older scanner would have the capabilities of communicating. What's going on is that the DLC in your truck communicates on GM's older serial data circuit instead of the newer class 2 protocol which newer scanners use. The trick is to pull the codes manually using the MIL / check engine light (service engine soon indicator.) Jumping terminals A and B will cause the MIL to flash with the key on, engine off.

Since last post, my engine light went off and stayed off in the winter...November through May...and came back on again. I did use factory plugs, so coincidence. Will the summer heat and/or change to winter/summer gasoline affect the O2 sensors?

Never bothered on my 99, but only 58,000 on it. I looked back at your first post, o2 and converter changed 120,000 ago. Not sure what you have there, see if it is the same code.
#82 of 95 O2 Sensor Heater
Nov 19, 2010 (6:44 pm)
I have a 2004 S10 with 6 cyl engine & 68,000 miles. Service Engine light comes on & sets code 0155 O2 sensor heater circuit malfunction Bank 2 sensor 1. Its been in the shop of a local auto repair chain three times & the Service engine light comes back on with in a day. Shop says they replaced the O2 sensors & heaters twice & checked all the connections. It has also been in my local Chevy dealer & they can't fix it. They tell me it is a computer glitch & want to replace the computer. Any one else have this problem?? Also is the O2 sensor heater a seperate unit or part of the O2 sensor. If it is a seperate unit where is it located & how hard is it to change???

Heater and sensor are the same unit.

Thank you for the info. That is what the repair shop told me but I was beginning to doubt them.
