Default Check Engine Light - Code 7 Throttle Position Sensor?

Hey everyone,

My 89 DX with a stock D15B2 is throwing a Check Engine Light, code 7. I know that I need a replacement Throttle Position Sensor, but I'm told that they're only sold new from the dealer attached to an entire throttle body, which I don't need.

Here's my problem - I know that some sites like streetimport and Ebay sell new Throttle position sensors, but every site I've seen says that they won't fit the 88-91 DX. (like this one http://www.streetimports.com/p...d=991 )

Can anyone show me where I can buy a new Throttle Position Sensor that will fit my D15B2? I'm pretty far from any junkyards right now so I can't just easily go and pull one off.

thanks,
Jason

the dual point TPS is different from a non dual point tps. from what i hear u can still use a non dual point tps but u have to swap 2 of the 3 wires around. do some searching and you will find what im talking about.

Sorry that is wrong..
The DX sensor is the exact opposite in design and
operates in the opposite direction.

Before you replace it,
Go through these two flowcharts and make sure it is bad:

I'd ohm the ground circuit. There is a TSB in regards to the TPS ground circuit.
It's for occasional Idle but, it wouldn't hurt to perform the TSB if not already.

Notes


91honda04

Bulletin No.
91-031

Issue Date
NOV. 1, 1991

File Under
ENGINE

Model

'89-91
CIVIC

Applicable To
SEE VEHICLES
AFFECTED

Occasional Rough Idle

SYMPTOM

1. The engine may occasionally idle roughly or erratically after coming to a stop with the throttle fully-closed.

2. On 1990-91 cars equipped with automatic transmission: Even though the proper procedure is followed, the shift interlock system may occasionally prevent the driver from shifting out of Park.


VEHICLES AFFECTED

All 1988-91 Civic models equipped with 1.5 liter engine and dual-point injection, thru VIN:

1HGED3...ML011574 (Sedan)
2HGED6...MH512869 (Hatchback)
JHMED3...MS031565 (Sedan)
JHMED8...MS012826 (CRX DX)
JHMEE2...MS004778 (2WD Wagon)

PROBABLE CAUSE

Inadequate grounding of the throttle angle sensor circuit.

CORRECTIVE ACTION

Replace the existing ground wire with the new ground harness listed under PARTS INFORMATION.

1. Disconnect the three-pin connector from the throttle angle sensor.

2. Remove the GRN/WHT wire from the three-pin connector with Pin Tool E, T/N 07JAZ-002050A, from the Terminal Pin Repair Kit (see TOOL INFORMATION).








3. Cut off the GRN/WHT wire as close as possible to the gray tape wrapping the wire harness. Discard the cut off piece.

4. Install the terminal end of the new ground harness into the three-pin connector. Gently pull on the wire to insure the pin is securely locked in the connector.








5. Route the new harness under the existing harness. Hold the harnesses together by wrapping them with 3M 33+ high-temperature electrical tape or equivalent. Wrap the tape as shown, making sure it completely covers the gray tape and any exposed end of the GRN/WHT wire.








6. Remove the bolt holding the harness bracket to the intake manifold. Install the eyelet on the new harness between the bracket and the manifold and reinstall the bolt.

NOTE: The harness eyelet must be installed as explained above. If it is installed between the bolt head and the bracket, the symptoms may not be corrected.


7. Reconnect the three-pin connector to the throttle angle sensor.

8. Test drive the car. Verify that it idles smoothly and at the proper speed.

Default Re: Check Engine Light - Code 7 Throttle Position Sensor?

rather then start a new thread i might as well bum this one since i hit a code 7 problem today...does anybody know if the tps sensor on a dpfi d15b2 motor is replaceable or do i have to change the whole throttle body with tps sensor attached...it appears that the tps sensor doesn't have screws to replace it on the dpfi throttle body.

i have been having a code 16 problem for the longest time but always clear it by swapping main relays and resetting the ecu...today i was driving and my cel came on and it was throwing a code 7...when i came to a stop my car would start to idle rough and fluctuate on neutral...i swapped out my main relay and reset the ecu again and the cel did not come back on but i haven't taken it for a test drive at high speeds yet...any tips would be appreciated...!!!

file a line through the rivets and try to unscrew it with a flathead.

this should prove useful although this guy goes about it a different way.

http://www.honda-tech.com/showthread.php?t=2193100

if you have access to a dremel or angle air tool with a cutting disc then i would simply cut a groove into the metal so that you can back it out with a flathead.
